[PATCH 0/4] drm/sun4i: rgb and dotclock misc fixes and improvements

[Chen-Yu Tsai]

Hi Maxime,

Here are a few small fixes and improvements to the sun4i drm driver.

Patch 1 declares the LCD panel RGB interface encoder and connector types
as MIPI DPI. AFAIK DPI is the parallel RGB variant.

Patch 2 fixes the weird clock rates I was getting on the dot clock when
testing the RGB-to-VGA bridge patches. You may want to queue this as a
fix for 4.8.

Patch 3 increases the dot clock divider upper bound by 1 to 127. AFAIK
127 is a valid divider. I doubt we will ever use it, since the parents
will go way higher than they are supposed to, but getting it right is
nicer.

Patch 4 changes the dot clock's behavior to make it round to the closest
clock rate. I think this would make it easier to match the LCD panel's
timings. More on the LCD timings in a later patch set.
