Subject: [PATCH v3 00/25] drm/sun4i: Allwinner A64 MIPI-DSI support 

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

Few comments from previous version still in discussion, but I just
send this version just to group all working changes together.
anyway I will fix in this in next version if any.

PLL_MIPI min rate is still weird, I tried many possible dclock rate
from panel driver to satisfy manual suggested min rate 500MHz but
none working so eventually moved 300MHz. any inputs on this area
are welcome.

All these changes are tested in 2-lane, 4-lane MIPI-DSI panels.

If anyone wants to test, use this repo [2] with WIP-A64-DSI branch.

Any inputs,
Jagan.
