Merge commit 'refs/for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next 

Picking up pace on the upstreaming of Komeda driver, with quite a lot
of new features added this time. On top of that we have the small
cleanups and improved usage of the debugfs functions. Please pull!

* Split is introduced for workaround scaler's input/output size limitation.
* The idea is simple, if one scaler can not fit the requirement, use two.
* So split splits the big source image to two half parts (left/right) and do
* the scaling by two scaler separately and independently.
* But split also imports an edge problem in the middle of the image when
* scaling, to avoid it, split isn't a simple half-and-half, but add an extra
* pixels (overlap) to both side, after split the left/right will be:
* - left: [0, src_length/2 + overlap]
* - right: [src_length/2 - overlap, src_length]
* The extra overlap do eliminate the edge problem, but which may also generates
* unnecessary pixels when scaling, we need to crop them before scaler output
* the result to the next stage. and for the how to crop, it depends on the
* unneeded pixels, another words the position where overlay has been added.
* - left: crop the right
* - right: crop the left
*
* The diagram for how to do the split
