This series adds support for the dsi and dphy controllers on the
Rockchip RK3568. I can confirm that for the Rockchip RK3568 this
current series DOES WORK now, but it requires rolling back clk changes
made for the HDMI driver. If the clock changes are not rolled back, the
image on the screen is shifted about 100 pixels to the right.

Clk changes in question:

Tested on an Anbernic RG503 and RG353P with clock changes rolled back,
the hardware works correctly on both devices.

Changes since RFCv1:
 - Identified cause of image shift (clock changes).
 - Noted that driver works now.
 - Added devicetree nodes for rk356x.dtsi.

Hello,
What other patches would I need to apply to test this series
on Anbernic RG503?

Best Regards,
Maya Matuszczyk

In addition to these patches you'd need the devicetree series:
https://lore.kernel.org/linux-rockchip/20220906210324.28986-1-macroalpha82@gmail.com/

You'd need the panel driver:
https://lore.kernel.org/dri-devel/20220906183642.12505-1-macroalpha82@gmail.com/

And you'd need to update the binding for the panel in the devicetree
(example here):
https://gist.github.com/macromorgan/caff01bfe4df6995d5f74cef701ede6d

If you apply these patches and roll back the clock driver changes the
panel should start working for you as it does for me. I tested by
nuking my build-tree and starting fresh with just these patches.
