This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M64 board.
DSI panel connected via board DSI port with,
- DLDO1 as VCC-DSI supply
- DCDC1 as VDD supply
- PD7 gpio for lcd enable pin
- PD6 gpio for lcd reset pin
- PD5 gpio for backlight enable pin

Add MIPI DSI pipeline for Allwinner A64.
- dsi node, with A64 compatible since it doesn't support
DSI_SCLK gating unlike A33
- dphy node, with A64 compatible with A33 fallback since
DPHY on A64 and A33 is similar
- finally, attach the dsi_in to tcon0 for complete MIPI DSI

The MIPI DSI controller in Allwinner A64 is similar to A33.
But unlike A33, A64 doesn't have DSI_SCLK gating so add compatible
for Allwinner A64 with uninitialized has_mod_clk driver.

This is v10 version for Allwinner A64 MIPI-DSI support
and here is the previous version set[1].
This series on top of drm-misc/for-linux-next along with video start
delay fix [2]
Changes for v10:
- updated dt-bindings as per .yaml format
- rebased on drm-misc/for-linux-next
Changes for v9:
-
As per the user manual, look like mod clock is not mandatory
for all Allwinner MIPI DSI controllers, it is connected to
CLK_DSI_SCLK for A31 and not available in A64.
So add has_mod_clk quirk and process the clk accordingly.

The MIPI DSI PHY controller on Allwinner A64 is similar
on the one on A31.
Add A64 compatible and append A31 compatible as fallback.

The MIPI DSI controller in Allwinner A64 is similar to A33.
But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to with separate compatible for A64 on the same driver.
