32f0a6ddc8 media: venus: Use on-chip interconnect API
This aims to add a requests for bandwidth scaling depending
on the resolution and framerate (macroblocks per second). The
exact value of the requested bandwidth is get from a
pre-calculated tables for encoder and decoder.

7e86efa2ff media: cec-gpio: add notifier support
Add support for cec-notifier to the cec-gpio driver.

This makes it possible to associate the CEC gpio pin with an HDMI
connector. This feature was always documented in the cec-gpio bindings:

Documentation/devicetree/bindings/media/cec-gpio.txt

But support for the hdmi-phandle property was never actually implemented in
this driver.

This patch adds support for this property.

It also fixes a few incorrect error returns in the probe() function, which
skipped the call to cec_delete_adapter().

Tested on a Raspberry Pi 3B with a modified vc4 driver.

2f39cce963 media: remove redundant 'default n' from Kconfig-s
'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.

Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:

    ...
    One side effect of (and the main motivation for) this change is making
    the following two definitions behave exactly the same:

        config FOO
                bool

        config FOO
                bool
                default n

    With this change, neither of these will generate a
    '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
    That might make it clearer to people that a bare 'default n' is
    redundant.

b7778c4668 media: platform: meson: Add Amlogic Meson G12A AO CEC Controller driver
The Amlogic G12A SoC embeds a second CEC controller with a totally
different design.

The two controller can work in the same time since the CEC line can
be set to two different pins on the two controllers.

This second CEC controller is documented as "AO-CEC-B", thus the
registers will be named "CECB_" to differentiate with the other
AO-CEC driver.

Unlike the other AO-CEC controller, this one takes the Oscillator
clock as input and embeds a dual-divider to provide a precise
32768Hz clock for communication. This is handled by registering
a clock in the driver.

Unlike the other AO-CEC controller, this controller supports setting
up to 15 logical addresses and supports the signal_free_time settings
in the transmit function.

Unfortunately, this controller does not support "monitor" mode.

63604a143f media: seco-cec: fix building with RC_CORE=m
I previously added an RC_CORE dependency here, but missed the corner
case of CONFIG_VIDEO_SECO_CEC=y with CONFIG_RC_CORE=m, which still
causes a link error:

drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_probe':
seco-cec.c:(.text+0x1b8): undefined reference to `devm_rc_allocate_device'
seco-cec.c:(.text+0x2e8): undefined reference to `devm_rc_register_device'
drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_irq_handler':
seco-cec.c:(.text+0xa2c): undefined reference to `rc_keydown'

Refine the dependency to disallow building the RC subdriver in this case.
This is the same logic we apply in other drivers like it.

Without the MFD driver, we run into a link error:

As we can compile-test all the dependency, the extra '| COMPILE_TEST' is
not needed to get the build coverage, and we can simply turn MFD_CROS_EC
into a hard dependency to make it build in all configurations.

Commit 1d38971438 ("[media] v4l: rcar_fdp1: add FCP dependency") fixed
a compilation breakage when the optional VIDEO_RENESAS_FCP dependency is
compiled as a module while the rcar_fdp1 driver is built in. As a side
effect it disabled compilation on Gen2 by disallowing the valid
combination ARCH_RENESAS && !VIDEO_RENESAS_FCP. Fix it by handling the
dependency the same way the vsp1 driver did in commit 199946731f

This driver is part of the cros-ec MFD and will be add as a sub-device when
the feature bit is exposed by the EC.

The controller will only handle a single logical address and handles
all the messages retries and will only expose Success or Error.

The controller will be tied to the HDMI CEC notifier by using the platform
DMI Data and the i915 device name and connector name.

The Renesas Fine Display Processor driver is used on Renesas R-Car SoCs

than the legacy ARCH_SHMOBILE, hence use the former.

This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near

4cff79e933 media: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Note:
  - The various VIDEOBUF*DMA* symbols had to loose their dependencies on
    HAS_DMA, as they are selected by several individual drivers.

9d2d60687c media: tegra-cec: add Tegra HDMI CEC driver
This driver adds support for the Tegra CEC IP. It is based on the
NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel.

This has been converted to the CEC framework and cleaned up.

Tested with my Jetson TK1 board. It has also been tested with the
Tegra X1 in an embedded product.

Note of warning for the Tegra X2: this SoC supports two HDMI outputs,
but only one CEC adapter and the CEC bus is shared between the
two outputs. This is a design mistake and the CEC adapter can
control only one HDMI output. Never hook up both HDMI outputs
to the CEC bus in a hardware design: this is illegal as per the
CEC specification.

The CEC bus can be shared between multiple inputs and zero or one
outputs, but not between multiple outputs.

f7e7b48e6d [media] rockchip/rga: v4l2 m2m support
Rockchip RGA is a separate 2D raster graphic acceleration unit. It
accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness

The driver supports various operations from the rendering pipeline.
 - copy
 - fast solid color fill
 - rotation
 - flip
 - alpha blending

The code in rga-hw.c is used to configure regs according to operations
The code in rga-buf.c is used to create private mmu table for RGA.

db6321a1af media: platform: VIDEO_QCOM_CAMSS should depend on HAS_DMA
If NO_DMA=y:

    warning: (TOUCHSCREEN_SUR40 && VIDEO_TW68 && VIDEO_CX23885 && VIDEO_CX25821 && VIDEO_CX88 && VIDEO_SAA7134 && VIDEO_COBALT && VIDEO_QCOM_CAMSS) selects VIDEOBUF2_DMA_SG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA)

and

    ERROR: "bad_dma_ops" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!
    ERROR: "bad_dma_ops" [drivers/media/platform/qcom/camss-8x16/qcom-camss.ko] undefined!

VIDEO_QCOM_CAMSS selects VIDEOBUF2_DMA_SG, which bypasses its dependency
on HAS_DMA.  Make VIDEO_QCOM_CAMSS depend on HAS_DMA to fix this.
