      media: tegra-cec: add Tegra HDMI CEC driver · 9d2d6068
      由 Hans Verkuil 提交于 
      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.

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.

      media: cec-gpio: add HDMI CEC GPIO driver · 1e33936d
      由 Hans Verkuil 提交于 
      Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework.

While I have heard of SoCs that use the GPIO pin for CEC (apparently an
early RockChip SoC used that), the main use-case of this driver is to
function as a debugging tool.

By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example
it turns it into a CEC debugger and protocol analyzer.

With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed.

But of course it can also be used with any hardware project where the
HDMI CEC line is hooked up to a pull-up gpio line.

In addition this has (optional) support for tracing HPD changes if the
HPD is connected to a GPIO.

      [media] cec: Kconfig cleanup · 56a263aa
      由 Hans Verkuil 提交于 
      The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

      [media] v4l: rcar_fdp1: add FCP dependency · 1d389714
      由 Arnd Bergmann 提交于 
      Commit 4710b752 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the
v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1.

It calls into the FCP driver, but when there is no dependency, FCP might
be a module while FDP1 is built-in.

We have the same logic in VIDEO_RENESAS_VSP1, which also depends on
FCP not being a module when it is built-in itself.

      [media] platform: pxa_camera: add VIDEO_V4L2 dependency · ff681022
      由 Arnd Bergmann 提交于 
      Moving the pxa_camera driver from soc_camera lots the implied
VIDEO_V4L2 Kconfig dependency, and building the driver without
V4L2 results in a kernel that cannot link:

This adds back an explicit dependency.
