[PATCH v7 00/23] drm/sun4i: Allwinner A64 MIPI-DSI support

[Jagan Teki <jagan@amarulasolutions.com>]

Here is next version changes for Allwinner A64 MIPI-DSI support

This series grouped the changes like previous version[1] with different
sets to support three different panels types that can fit into the DSI
controller.

set:1, for 4-lane, burst mode support
- patch 0001: 0009, DSI controller changes that support burst mode.

set:2, for A64 DSI support
- patch 0010: tcon dclk divider computation based on A64 BSP. 
- patch 0011: 0017, Allwinner A64 DSI controller changes.

set:3, enable 4-lane burst mode panel:
- patch 0018: Overlay patch that enable Feiyang FY07024DI26A30-D
  burst mode panel on Pine64-LTS

set:4, enable 4-lane video mode panel:
- patch 0019: msg type MIPI_DSI_GENERIC_SHORT_WRITE_2_PARAM support
- patch 0020: Overlay patch that enable Bananapi S070WV20-CT16 ICN6211 
  panel on Bananapi M64

set:5, enable 2-lane video mode panel:
- patch 0021, 0022: DSI hfp and hbp timings fixes
- patch 0023: Enable Techstar TS8550B panel on Amarula A64-Relic

Changes for v7:
- moved vcc-dsi binding to required filed.
- drop quotes on fallback dphy bindings.
- drop min_rate clock pll-mipi patches.
- introduce dclk divider computation as like A64 BSP.
- add A64 DSI quark patches.
- fixed A64 DSI pipeline.
- add proper commit messages.
- collect Merlijn Wajer Tested-by credits.
Changes for v6:
- dropped unneeded changes, patches
- fixed all burst mode patches as per previous version comments
- rebase on master
- update proper commit message
- dropped unneeded comments
- order the patches that make review easy
Changes for v5:
- collect Rob, Acked-by
- droped "Fix VBP size calculation" patch
- updated vblk timing calculation.
- droped techstar, bananapi dsi panel drivers which may require
  bridge or other setup. it's under discussion.
Changes for v4:
- droppoed untested CCU_FEATURE_FIXED_POSTDIV check code in
  nkm min, max rate patches
- create two patches for "Add Allwinner A64 MIPI DSI support"
  one for has_mod_clk quirk and other one for A64 support
- use existing driver code construct for hblk computation
- dropped "Increase hfp packet overhead" patch [2], though BSP added
  this but we have no issues as of now.
  (no issues on panel side w/o this change)
- create separate function for vblk computation 
- enable vcc-dsi regulator in dsi_runtime_resume
- collect Rob, Acked-by
- update MAINTAINERS file for panel drivers
- cleanup commit messages
- fixed checkpatch warnings/errors
