The Rockchip VOP driver has a function, scl_vop_cal_scl_fac, that will
lookup the drm_format_info structure from the fourcc passed to it by its
caller.
However, its only caller already derefences the drm_format_info structure
it has access to to retrieve that fourcc. Change the prototype of that
function to pass the drm_format_info structure directly, removing the need
for an extra lookup.

drm_format_num_planes() is basically a lookup in the drm_format_info table
plus an access to the num_planes field of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to drm_format_num_planes is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry

Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

So far, the drm_format_plane_cpp function was operating on the format's
fourcc and was doing a lookup to retrieve the drm_format_info structure and
return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent. In order to be extra consistent, also rename that
function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

However, this is inefficient since in most cases, we will have the

Let's follow the latter pattern and remove the extra lookup while being a

In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

drm_get_format_info directly calls into drm_format_info, but takes directly
a struct drm_mode_fb_cmd2 pointer, instead of the fourcc directly. It's
shorter to not dereference it, and we can customise the behaviour at the
driver level if we want to, so let's switch to it where it makes sense.

drm_format_info_plane_cpp() basically just returns the cpp array content
found in the drm_format_info structure.
Since it's pretty trivial, let's remove the function and have the users use
the array directly

Same comment about plane being int instead of unsigned int, but I think we

Another thing that I find odd is that the division by vsub/hsub is not
rounded up, but again, it's something independent from your patch.
