[PATCH 00/12] drm/sun4i: Allwinner A64 MIPI-DSI support

This series add MIPI-DSI support on Allwinner A64. The same A31 controller
is reused and tweaked for A64 since the register space for both SoC's look same.

The current clock rate (270MHz) with nkm (5,2,11) from PLL_MIPI is unable to work
with A64 DSI block. I've tested with few changes to verify desired nkm divider
values (1, 2, 5) but with existing nkm divider logic(ccu_nkm_find_best) I'm unable
to figure out the desired clock rate, anyone suggestion please let me know here.

Bananapi S070WV20-CT16 DSI panel with BPI-M64 board works fine,
but will figure out and fix the clock logic in next versions.

Thanks,
Jagan.
