a584e2c301 drm/meson: dw-hdmi: disable DW-HDMI CEC sub-driver
On the Amlogic SoCs, the DW-HDMI HW support is here but the DW-HDMI CEC signal
is not connected to a physical pin, leading to confusion when the dw-hdmi cec
controller can't communicate on the bus.

Disable it to avoid exposing a non-functinal bus.

drm: Use state helper instead of the plane state pointer
Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.

Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.

This was made using the coccinelle script below:

drm: Rename plane->state variables in atomic update and disable
Some drivers are storing the plane->state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.

In order to ease subsequent reworks and to avoid confusing or

820c170717 drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

b33340e33a drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP registers
Removing the meson-dw-hdmi module and re-inserting it results in a hang
as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen
when booting with mainline u-boot and using the u-boot provided DT (which
is highly desirable).

The reason for the hang seem to be that the clocks are not always
enabled by the time we enter meson_dw_hdmi_init(). Moving this call
*after* dw_hdmi_probe() ensures that the clocks are enabled.

70a59dd829 drm/<drivers>: Constify struct drm_driver
Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
  Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
  platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
  maybe a bit too much, hence the num_ioctls assignment prevents a
  const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
  from me.
- legacy drivers, because legacy requires non-const drm_driver.

Note that for armada I also went ahead and made the ioctl array const.

Only cc'ing the driver people who've not been converted (everyone else
is way too much).

v2: Fix one misplaced const static, should be static const (0day)

v3:
- Improve commit message (Sam)

drm/atomic: Pass the full state to CRTC atomic begin and flush
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's start convert all the remaining helpers to provide a consistent
interface, starting with the CRTC's atomic_begin and atomic_flush.

The conversion was done using the coccinelle script below, built tested on
all the drivers and actually tested on vc4.

drm/atomic: Pass the full state to CRTC atomic enable/disable
If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.

In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.

It's not expected to overflow these fields, but the compiler did
find a case where it overflows.
We can safely ignore this, so mask the value with the field width.

17f64701ea drm/meson: viu: fix setting the OSD burst length in VIU_OSD1_FIFO_CTRL_STAT
The burst length is configured in VIU_OSD1_FIFO_CTRL_STAT[31] and
VIU_OSD1_FIFO_CTRL_STAT[11:10]. The public S905D3 datasheet describes
this as:
- 0x0 = up to 24 per burst
- 0x1 = up to 32 per burst
- 0x2 = up to 48 per burst
- 0x3 = up to 64 per burst
- 0x4 = up to 96 per burst
- 0x5 = up to 128 per burst

The lower two bits map to VIU_OSD1_FIFO_CTRL_STAT[11:10] while the upper
bit maps to VIU_OSD1_FIFO_CTRL_STAT[31].

Replace meson_viu_osd_burst_length_reg() with pre-defined macros which
set these values. meson_viu_osd_burst_length_reg() always returned 0
(for the two used values: 32 and 64 at least) and thus incorrectly set
the burst size to 24.

Replace the drm_connector pointer passed to the .mode_valid() function
with a const drm_display_info pointer, as that's all the function should
need. Use the display info passed to the bridge .mode_valid() operation
instead of retrieving it from the connector, to prepare for make
connector creation optional.

9bc78d6dc8 drm: meson: dw-hdmi: Use dw_hdmi context to replace hack
The meson-dw-hdmi driver needs to access its own context from the
.mode_valid() operation. It currently gets it from the dev_private field
of the drm_device retrieved from the connector, which is a hack. Use the
private data passed to the .mode_valid() operation instead.

96591a4b93 drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()
Platform glue drivers for dw_hdmi may need to access device-specific
data from their .mode_valid() implementation. They currently have no
clean way to do so, and one driver hacks around it by accessing the
dev_private data of the drm_device retrieved from the connector.

Add a priv_data void pointer to the dw_hdmi_plat_data structure, and
pass it to the .mode_valid() function.

bd9ff7b521 drm/meson: Drop explicit drm_mode_config_cleanup call
It's right above the drm_dev_put().

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

Aside: This driver gets its devm_ stuff all wrong wrt drm_device and
anything hanging off that. Not the only one unfortunately.

v2: Explain why this cleanup is possible (Laurent).

8496a2172d drm/meson: Add YUV420 output support
This patch adds support for the YUV420 output from the Amlogic Meson SoCs
Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.
In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.

This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.

This patch enables the bridge bus format negociation, and handles
the YUV420 case if selected by the negociation.

e5fab2ec9c drm/meson: vclk: add support for YUV420 setup
This patch adds clocking support for the YUV420 output from the
Amlogic Meson SoCs Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.

This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.

This patch adds the TMDS PHY clock value in all the video clock setup
in order to better support these specific uses cases and switch
to the Common Clock framework for clocks handling in the future.
