[PATCH] v4l: vsp1: Disable HSV formats on Gen3 hardware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While all VSP instances can process HSV internally, on Gen3 hardware
reading or writing HSV24 or HSV32 from/to memory causes the device to
hang. Disable those pixel formats on Gen3 hardware.
