[PATCH] drm/mcde: Retry DSI read/write transactions

2020-07-30 Thread Linus Walleij
The vendor driver makes a few retries on read DSI transactions, something that is needed especially in case of read (such as reading the panel MTP ID) while the panel is running in video mode. This happens on the Samsung s6e63m0 panel on the Golden device. Retry reads and writes alike two times.
