[PATCH v9 0/3] Add support for the S6E3HA2 panel on TM2 board

[Hoegeun Kwon]

Changes for V9:
- Fixed the te-gpio to optional in bindings

Changes for V8:
- Applied below two patches: (drm/exynos)
  : drm/exynos: mic: Add mode_set callback function
  : drm/exynos: mic: Fix parse_dt function
- The dt-binding patch and driver patch were divided.
- Rebase these patches on samsung SoC tree[1] and tm2 touckey patch[2].

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 patch2?
  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.
