[v5,00/17] drm/sun4i: Allwinner A64 MIPI-DSI support

Message

This series fixed the issues related to work DSI on 2-lane panel
which is reported on previous version[1][2][3]

This supposed to be a clean series, where it support Allwinner A64 MIPI-DSI
support for 4-lane, 2-lane DSI panels.

This series fixed all previous series comments along with checkpatch
warnings/error.

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

[2] https://patchwork.kernel.org/patch/10657541/
[1] https://patchwork.kernel.org/patch/10657619/

Note: the respetive dts consumer for dsi will send once the panel
driver finalized or in burst mode patch series.

Any inputs,
Jagan.
