Series drm/sun4i: dsi: Support the A100/D1 controller variant | expand

Commit Message

Samuel Holland Aug. 12, 2022, 7:42 a.m. UTC 
The A100 variant of the MIPI DSI controller now gets its module clock
from the TCON via the TCON TOP, so the clock rate cannot be set to a
fixed value. Otherwise, it appears to be the same as the A31 variant.
