drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

Vblank interrupts for hdmi are handled by mixer internally because drm

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send

images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv

define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.

handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
- vp layer support

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls

drm/exynos: added hdmi display support
This patch is hdmi display support for exynos drm driver.
There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv
and some low level code is already in s5p-tv and even headers for register
define are almost same. but in this patch, we decide not to consider separated
common code with s5p-tv.
Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc.
1. mixer. The piece of hardware responsible for mixing and blending multiple
data inputs before passing it to an output device. The mixer is capable of
handling up to three image layers. One is the output of VP. Other two are
images in RGB format. The blending factor, and layers' priority are controlled
by mixer's registers. The output is passed to HDMI.
2. vp (video processor). It is used for processing of NV12/NV21 data. An image
stored in RAM is accessed by DMA. The output in YCbCr444 format is send to
mixer.
3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes
pixel data from mixer and transforms it into data frames. The output is send
to HDMIPHY interface.
4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to
HDMI connector. Basically, it contains a PLL that produces source clock for
mixer, vp and hdmi.
5. ddc (display data channel). It is dedicated i2c channel to exchange display
information as edid with display monitor.
With plane support, exynos hdmi driver fully supports two mixer layes and vp
layer. Also vp layer supports multi buffer plane pixel formats having non
contigus memory spaces.
In exynos drm driver, common drm_hdmi driver to interface with drm framework
has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as
sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls
them. mixer controls all overlay layers in both mixer and vp.
Vblank interrupts for hdmi are handled by mixer internally because drm
framework cannot support multiple irq id. And pipe number is used to check
which display device irq happens.
History
v2: this version
- drm plane feature support to handle overlay layers.
- multi buffer plane pixel format support for vp layer.
