Hi Andrzej,
Thank you for your review.
The purpose of this patch is add support for s6e63j0x03 AMOLED panel
on the rinato board(Samsung Galaxy Gear 2).
Changes for V4:
- Added Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> (2/3 patch).
- Fixed the style of macro function.
Changes for V3:
- Applied patch 'ARM: dts: exynos: Fix the active of reset gpios from rinato dts' (v2 3/4)
- Remove the unnecessary define ('MIN_BRIGHTNESS')
- Removed explicit casting.
- Removed violation of kernel coding style.
Changes for V2:
- Added the interface info in binding document.
- Added Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> (1/3 patch).
- Added Acked-by: Rob Herring <robh@kernel.org> (1/3 patch).
- Fixed the tristate of config from video mode to command mode.
- Fixed the reset gpios from active high to low from rinato dts.
- Fixed a lot of things in panel driver, reflect Andrzej's review.
Best regards,
Hoegeun

This patch adds MIPI-DSI based S6E63J0X03 AMOLED LCD panel driver
which uses mipi_dsi bus to communicate with panel. The panel has
320×320 resolution in 1.63" physical panel. This panel is used in
Samsung Galaxy Gear 2.

This patch adds MIPI-DSI based S6E63J0X03 AMOLED LCD panel driver
which uses mipi_dsi bus to communicate with panel. The panel has
320×320 resolution in 1.63" physical panel. This panel is used in
Samsung Galaxy Gear 2.

* [PATCH v4 2/3] drm/panel: Add support for s6e63j0x03 panel driver
@ 2017-07-13 2:20 ` Hoegeun Kwon

To: linux-arm-kernel
This patch adds MIPI-DSI based S6E63J0X03 AMOLED LCD panel driver
which uses mipi_dsi bus to communicate with panel. The panel has
320?320 resolution in 1.63" physical panel. This panel is used in
Samsung Galaxy Gear 2.

The display-timing and delay are included in the panel driver. So it
should be removed in dts.
