Because imx-drm is actually a misnomer. The i.MX IPU is a multifunction
device, which as one part has the display controllers, but also camera
interfaces and mem-to-mem scaler devices, which are hooked up via the
V4L2 interface.

The generic IPU part, which is used for example for programming the DMA
channels is using V4L2 pixel formats as a common base. We have patches
to split this out and make this fact more visible. (The IPU core will be
placed aside the Tegra host1x driver)

Regards,
Lucas

Because imx-drm is actually a misnomer. The i.MX IPU is a multifunction
device, which as one part has the display controllers, but also camera
interfaces and mem-to-mem scaler devices, which are hooked up via the
V4L2 interface.

The generic IPU part, which is used for example for programming the DMA
channels is using V4L2 pixel formats as a common base. We have patches
to split this out and make this fact more visible. (The IPU core will be
placed aside the Tegra host1x driver)

Regards,
Lucas

Have you considered splitting thing up further and move out the display
controller driver to DRM and the camera driver to V4L2? I mean, if that
is even possible with a reasonable amount of work.

Is the "mem-to-mem" the same as the "DMA channels" you mentioned? If it
only does DMA, why does it even need to worry about pixel formats?

[PATCHv5][ 4/8] staging: imx-drm: Use de-active and pixelclk-active display-timings.

[Denis Carikli]

If de-active and/or pixelclk-active properties were set in the
display-timings DT node, they were not used.

Instead the data-enable and the pixel data clock polarity
were hardcoded.

This change is needed for making the eukrea-cpuimx51
  QVGA display work.

ChangeLog v3->v4:
- The old patch was named "staging: imx-drm: ipuv3-crtc: don't harcode some mode".
- Reworked the patch entierly: we now takes the mode flags from the device tree.

ChangeLog v2->v3:
- Added some interested people in the Cc list.
- Ajusted the flags to match the changes in "drm: Add the lacking
  DRM_MODE_FLAG_* for matching the DISPLAY_FLAGS_*"

ChangeLog v3->v5:
- Code clenaup.

ChangeLog v2->v3:
- Added some interested people in the Cc list.
- the lcd-supply is now called display-supply (not all display are LCD).
- The code and documentation was updated accordingly.
- regulator_is_enabled now guard the regulator enables/disables because
  regulator_disable does not check the regulator state.

I don't think this is necessary. There is code in the regulator core
nowadays that supplies a dummy regulator if one hasn't been hooked up in
devicetree explicitly. So any error that you get at this point is likely
a valid one rather than just a missing regulator.

The advantage is that you no longer have to check at every step of the
way that the regulator is valid before calling the regulator API.

[PATCHv5][ 6/8] ARM: dts: mbimx51sd: Add display support.

[Denis Carikli]

The CMO-QVGA, DVI-SVGA and DVI-VGA are added.

Cc: Shawn Guo <shawn.guo@linaro.org>
Cc: Sascha Hauer <kernel@pengutronix.de>
Cc: linux-arm-kernel at lists.infradead.org
Cc: Eric B?nard <eric@eukrea.com>
Signed-off-by: Denis Carikli <denis@eukrea.com>
---
ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.

ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51 boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
  might be annoyed by the receiving of that patch which is unrelated to their
  subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

The "status = " here should probably be in the board DTS, not in the LCD DTS.

The display is optional on the baseboard of the cpuimx51.

So my idea was to activate the display only for the configurations where 
it's used.

ChangeLog v3->v5:
- Updated to the new GPIO defines.

ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51 boards.
- This patch now only adds backlight support.
- Added some interested people in the Cc list, and removed some people that
  might be annoyed by the receiving of that patch which is unrelated to their
  subsystem.

[PATCHv5][ 8/8] ARM: imx_v6_v7_defconfig: Enable backlight gpio support.

[Denis Carikli]

The eukrea mbimxsd51 has a gpio backlight for its
  LCD display, so we turn that driver on.
