We don't normally define two macros for each bit. You can drop the
F2B_LSB macro, rename F2B_MSB to F2B, and use BIT(12).

I would drop the last one as you don't use it.

Same here, one macro per bit.
The BRDITH_CTRL registers doesn't seem to be used. I don't mind adding
it though.

Please move this to vsp1_regs.h, just below the corresponding registers.
I would also prefer giving the macros names that related to the
registers.

Please wrap this as
if ((entity->vsp1->version & VI6_IP_VERSION_MODEL_MASK) ==
VI6_IP_VERSION_MODEL_VSPD_GEN4) {
You could also test entity->vsp1->gen == 4, up to you.

While this matches the detailed bit order of the V4L2 format as defined
in patch 1/7, it doesn't match the XBGR2101010 name, at least if
interpreted the same way as DRM_FORMAT_XBGR2101010. I think this should
be DRM_FORMAT_RGBX1010102 instead.
Same for the nex two formats, they should be RGBA1010102 and
ARGB2101010.
