From: Chris Morgan <macromorgan@hotmail.com> 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: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/clk/rockchip/clk-rk3568.c?id=ff3187eabb5ce478d15b6ed62eb286756adefac3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/clk/rockchip/clk-rk3568.c?id=6e69052f01d9131388cfcfaee929120118a267f4 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.
