From: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>
The format lookup (and enumeration) functions take a boolean flag to
tell if Bayer formats should be considered. This leads to hard to read
lines such as
return enum_format(fourcc, NULL, index, cs_sel, true, false);
where the boolean parameters can easily be mixed. To make the code
clearer, add a CS_SEL_BAYER flag that can be passed through the
codespace_sel parameter of the lookup functions to replace the bool
parameter.
slongerbeam:
- The original patch declared CS_SEL_ANY as a bitfield containing only
CS_SEL_YUV | CS_SEL_RGB. It makes more sense to declare CS_SEL_ANY
as all of the above (YUV, RGB, BAYER). A new enum is also declared
for the YUV | RGB selection as CS_SEL_YUV_RGB, and that is used by
sub-devices that don't support BAYER and only allow selecting and
enumerating YUV or RGB encodings. CS_SEL_ANY is now only used by the
CSI sub-devices and the attached capture interfaces, since only those
devices support BAYER formats.
