Hi,
This series adds LCD I80 interface display support for Exynos DRM driver. The FIMD(display controller) specification describes it as "LCD I80 interface" and the DSI specification describes it as "Command mode interface".
This is 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 V2: http://www.spinics.net/lists/dri-devel/msg59867.html V3: http://www.spinics.net/lists/dri-devel/msg60708.html V4: http://www.spinics.net/lists/dri-devel/msg60943.html V5: http://www.spinics.net/lists/dri-devel/msg62956.html
Changelog v2:
- Fixes typo and removes unnecessary error log. (commented by Andrzej Hazda)
- Adds missed pendlig_flip flag clear points. (commented by Daniel Kurtz)
Changelog v3:
- Removes generic command mode and command mode display timing interface.
- Moves I80 interface timings from panel DT to the FIMD(display controller) DT.
Changelog v4:
- Removes exynos5 sysreg(syscon) DT bindings and node from dtsi because it was already updated by linux-samsung-soc. (commented by Vivek Gautam)
Changelog v5:
- Fixes FIMD vidcon0 register relevant code.
- Fixes panel gamma table, disable sequence.
- Slitely updates for code cleanup.
Changelog v6:
- Removes pass TE host ops in dsi and exynos dsi uses TE irq handler instead, and it is related with the TE GPIO of panel. (commented by Thierry Reding)
Patches 1 and 2 fix trivial bugs.
Patches 3, 4, 5 and 6 implement FIMD(display controller) I80 interface. The MIPI DSI command mode based 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 generates it and the dsi should receive the TE IRQ and call TE handler chains to notify it to the FIMD.
Patches 7 and 8 implement to use Exynos5410 / 5420 / 5440 SoC DSI driver which is different from previous Exynos4 SoCs for some registers control.
Patches 9 and 10 introduce MIPI DSI command mode based Samsung S6E3FA0 AMOLED 5.7" LCD drm panel driver.
The ohters add DT property nodes to support MIPI DSI command mode.
I welcome any comments.
Thank you. Best regards YJ

Piked them up except patch 9 and 10. The two patches are needed for more review and consensus
Thanks, Inki Dae
