In the VEC driver, enable mapping VEC (not DPI) to DPI GPIOs. This is to support VEC output over GPIO on Raspberry Pi CM5. It is harmless as DPI and VEC could not be used concurrently, and the output is anyway conditional on pinctrl. Also, tweak the style of VIDEO_OUT_CFG register definitions (in both DPI and VEC drivers) to be more Linux-friendly. Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>

There was a problem hiding this comment.
^ The register style change somewhat obscures it; the functional change is this line only.

Tested RP1 VEC and DPI, both still work as expected (apart from RPi-Distro/repo#397) |
