Subject: [PATCH v11 0/7] drm/sun4i: dsi: Fixes/updates (A33 reworked!)

This is v11 version changes for previous series[1].

This series dropped the tcon->dclk_min_div and tcon->dclk_max_div
patches, since the discussion on the respective threads[2][3] 
not finalized or not agree on both the ends.

This series mostly the commit messages changes suggested by Chen-Yu.

Most of these issues are reproduced while supporting Allwinner A64
MIPI-DSI [4] but to confirm it with other SoC this series is reworked
on A33 since the controller tested it A33 as of now.

Since we don't have proper evidence and documentation for dsi controller
in Allwinner, these changes are more likely to rely on new working BSP
codes (even the initial driver written as per this rule).

All these fixes/updates are tested in "bananapi,s070wv20-ct16" panel
on Allwinner A33, the same panel timings are available in panel-simple
in mainline tree.

Changes for v11:
- Drop DCLK dividers patches
- Updated the commit message changes suggested by Chen-Yu
- rebased on linux-next
Changes for v10:
- reworked previous "Fixes/updates" patches on A33
- reworked previous A64 DSI fixes on A33
- added proper detailed commit messages with logs
- tested on BPI-M2M board.
Changes for v9:
- rebase on drm-misc
- update commit messages
- add hsync_porch overflow patch
Changes for v8:
- rebase on master
- rework on commit messages
- rework video start delay
- include drq changes from previous version
Changes for v7:
- rebase on master
- collect Merlijn Wajer Tested-by credits.
Changes for v6:
- 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, v4, v3, v2:
- use existing driver code construct for hblk computation
- create separate function for vblk computation
- cleanup commit messages
- update proper commit messages
- fixed checkpatch warnings/errors
- use proper return value for tcon0 probe
- add logic to get tcon0 divider values
- simplify timings code to support burst mode
- fix drq computation return values
- rebase on master

Any inputs?
Jagan.
