[PATCH v6 00/22] drm/sun4i: Allwinner A64 MIPI-DSI support

[Jagan Teki]

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

This series grouped the changes from previous version A64 MIPI-DSI[1]
along with burst mode[2].

Though the series seems to have more patches, but all patches are ordered 
in a way that the review process is as smooth as possible.

Overall the series is grouped into four different sets to support three 
different panels types that can fit into the DSI controller.

set:1 for 4-lane, burst mode:
- patch 0001: 0009, DSI controller changes that support burst mode.
  all the patches fixed the previous comments along with proper commit message.

set:2 for A64 DSI changes:
- patch 0010: 0011, PLL-MIPI changes related to A64
- patch 0012: 0013, VCC-DSI supply change on DSI controller
- patch 0014: 0015: dt-bindings patches for A64 DSI and DPHY documentation
- patch 0016: A64 DSI pipeline patch
- patch 0017: Overlay patch that enable Feiyang FY07024DI26A30-D burst mode
  panel on Pine64-LTS to validate set:1 changes

set:3 for 4-lane, non-burst mode:
- patch 0018: msg type MIPI_DSI_GENERIC_SHORT_WRITE_2_PARAM support
- patch 0019: Overlay patch that enable Bananapi S070WV20-CT16 ICN6211 
  panel on Bananapi M64 to validate set:3 changes

set:4 for 2-lane, non-burst mode:
- patch 0020: 0021, DSI hfp and hbp timings fixes
- patch 0022: patch to enable Techstar TS8550B panel on Amarula A64-Relic
  to validate set:4 changes.

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
