[PATCH v2 00/18] drm/exynos: support MIPI DSI command mode display

[YoungJun Cho]

Hi,

This series is for the Exynos DRM driver to support MIPI DSI command mode
display and based on exynos-drm-next branch.

The previous patches,
RFC: http://www.spinics.net/lists/dri-devel/msg58898.html
V1: http://www.spinics.net/lists/dri-devel/msg59291.html

Changelog v2:
- Rebases for latest exynos-drm-next branch
- Fixes typo and removes unnecessary error log (commented by Andrzej Hazda)
- Adds missed pendlig_flip flag clear points (commented by Daniel Kurtz)

Patches 1 and 2 fix trivial bugs.

Patches 3 and 4 introduce command mode and command mode display timing.
These are based on video mode and (video mode) display timing.
The MIPI DSI command mode interface panel does not require (video mode) display
timing, but it requires signal timings to distinguish command data and video
data so command mode and command mode display timing are used for it.

Patch 5 converts command mode to drm display mode.

Patches 6, 7, 8, 9 and 10 implement FIMD(display controller) I80 interface.
The MIPI DSI command mode interface panel generates Tearing Effect
synchronization signal between MCU and FB to display video image,
and FIMD should trigger to transfer video image at this signal.
So the panel should receive the TE IRQ then calls TE handler chains to notify
it to the FIMD.

Patches 11 and 12 implement to use Exynos5420 SoC DSI driver which is different
from previous Exynos4 SoCs for some registers control.

Patches 13 and 14 introduce MIPI DSI command interface Samsung S6E3FA0 AMOLED
5.7" LCD panel driver.

Patch 15 is device tree source file for Exynos4 SoCs to support MIPI DSI
command mode.

The others are device tree source files for Exynos5420 to support MIPI DSI
(command mode) driver.

I welcome any comments.

Thank you.
Best regards YJ
