This series extends the output color format support of the Rockchip DW HDMI QP controller to cover 10-bit YUV 4:2:2 and 8/10-bit YUV 4:2:0.
Patches 1, 7 & 15 improve VOP2 robustness on RK3588, helping recover from exceptions and preventing random display output glitches observed when switching modes that also change the color format, e.g. from RGB to YUV 4:2:0 and vice versa. Patch 8 avoids an incorrect DCLK source switch for 10-bit YUV 4:2:2 by forcing 8 bpc in the bandwidth check. Patches 2-6 address a few vop2 related issues reported by Sashiko, while 9-12 are additional cleanups/improvements. Patch 13 adds MEDIA_BUS_FMT_UYVY10_1X20 for 10-bit YUV 4:2:2 output, configuring the PHY with 8 bpc. YUV 4:2:2 always transmits two 12-bit components per pixel regardless of color depth, so from a clock-rate perspective it is equivalent to three 8-bit RGB components. Patch 14 advertises YUV 4:2:0 output, now that the bus-format and VOP2 support are in place. Tested on Radxa's boards ROCK 5B (RK3588) and ROCK 4D (RK3576).
