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

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