Subject: [PATCH v4 0/5] Add new panel driver Samsung S6E88A0-AMS427AP24

The patchset adds a new driver for Samsung AMS427AP24 panel with S6E88A0
controller. Patches are based on current branch drm-misc-next.

The discussion in v3 was not finished. I send v4 nonetheless as a new base to
continue the discussion. I hope that's ok.

Changes in v4:

 Patch 3
 - Removed include <linux/of.h>, it's not needed.
 - Added comments to the mipi_dsi_dcs_write_seq_multi() lines in function
   s6e88a0_ams427ap24_on().

 Patch 4
 - New defines for payload data length, thereof a fixed and a variable part.
 - In the array s6e88a0_ams427ap24_br_to_cd[] made the comment about the
   columns more clear and added an additional column "brightness from".
 - Array s6e88a0_ams427ap24_aid[] reduced from five to two columns and
   s6e88a0_ams427ap24_elvss[] from two to one column. Now they hold the
   variable data only. I kept s6e88a0_ams427ap24_elvss[] as a two-dimensional
   array to allow using the same memcopy procedure for all three buffers aid,
   elvss and gamma in function s6e88a0_ams427ap24_set_brightness().
 - In function s6e88a0_ams427ap24_set_brightness() initialized prototype
   payload array for b2 and b6 commands. And in the memcpy commands below
   used the new defines for the fixed and variable data length.

 Patch 5
 - Added a comment to the mipi_dsi_dcs_write_seq_multi() line, according to the
   other lines before and after.
