[PATCH v7 0/4] Add support for the S6E3HA2 panel on TM2 board

[Hoegeun Kwon]

Purpose of this patch is add support for S6E3HA2 AMOLED panel on
the TM2 board. The first patch adds support for S6E3HA2 panel
device tree document and driver, the second patch add support for
S6E3HA2 panel device tree.

Change for V7:
- Fixed the mode_set callback function of mic device driver.
  because the mic register is initialized when entering suspend
  mode, so should set the reg value whenever pre_enable is
  called.

Changes for V6:
- Fixed the parse_dt function of dsi device driver.
- Removed OF graph of panel in DT and DT binding document.
- Fixed the s6e3ha2 panel device driver.
  - Fixed from number size to ARRAY_SIZE().
  - Fixed error handling in mipi_dsi_dcs_* functions.
  - Fixed the clock of display_mode.
  - Removed unnecessary casting and error log.

Change for V5:
- The V5 has only one fix in V4 below.
- Removed the enable check of the mic driver in mode_set
  callback, because mode_set should be performed every time.

Changes for V4:
- Removed display-timings in devicetree, the display-timings has
  been fixed to be provided by the device driver.
- Added the mode_set callback function into exynos_drm_mic,
  because the exynos_drm_mic driver can not parse a videomode
  struct by removing the display-timings from the devicetree.

Changes for V3:
- In the DT binding document, made it clearly that the panel is a
  child node of dsi.
- Fix reset-gpio active from high to low.
- Is the OF graph saying related to [1]?
  Althogh the panel is a child of dsi, I think OF graph necessary.
  because if a remote-endpoint is not specified, the dsi also
  panel is not probed.
- The display-timings has been fixed to be provided by the device
  driver. however, I think display-timings is necessary in dts.
  because if dts does not have display-timings, dsi will not load.

Changes for V2:
- Fixed the samsung,s6e3ha2.txt DT document.
  - Added active high or low after the description of the GPIOs.
  - Removed the reg and added a description of the virtual
    channel number of a DSI peripheral.
