However, DE3 is more suited to work in YUV color space. Change CSC mode argument to format type to be more neutral. New argument only tells layer format type and doesn't imply output type. This commit doesn't make any functional change.

This comes from DE2 limitation, which doesn't have CSC unit for UI layers. However, DE3 has separate CSC units for each layer. This allows display pipeline to make output signal in different color spaces. To support both use cases, add a call to CSC setup function also in UI layer code. For DE2, this will be a no-op, but it will allow DE3 to output signal in multiple formats.

This could be inferred from the is_de3 flag alone, however this will not scale with addition of future DE versions in subsequent patches. Add a separate flag to signal this in the mixer configuration.

Add support for them. Currently it's implemented only for VI layers, but vendor code and documentation suggest UI layers can have them too. However, I haven't observed any SoC with such feature.

DE2 and DE3 are already supported by the mainline driver. The DE33 in the H616 has mixer0 and writeback units. The clocks and resets required are identical to the H3 and H5 respectively, so use those existing structs for the H616 description. There are two additional 32-bit registers (at offsets 0x24 and 0x28) which require clearing and setting respectively to bring up the hardware. The function of these registers is currently unknown, and the values are taken from the out-of-tree driver. Add the required clock description struct and compatible string to the DE2 driver.

Notable features (from the H616 datasheet and implemented): - 4096 x 2048 (4K) output support - AFBC ARM Frame Buffer Compression support - YUV420 input support The DE2 and DE3 engines have a blender register range within the mixer engine register map, whereas the DE33 separates this out into a separate display group, and adds a top register map. Extend the mixer to support the DE33.
