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.
