Subject: [PATCH 00/11] drm/msm/dpu: tweaks for better hardware resources
 allocation

This series include misc fixes related to hardware resource allocations
in the msm dpu driver, some specifically for msm8998 (including hw
catalog fixes and cursor sspp support for cursor planes, instead of
using Smart DMA pipes).

This series has been tested on msm8998 with additional patches to enable
hdmi support.

The following modetest example command works now; 8 planes can be
displayed simultaneously on msm8998 in 1080p, including a cursor plane,
using a single LM:

modetest -Mmsm -a \
    -s 32:1920x1080-60 \
    -P 33@87:1920x1080+0+0@...4 \
    -P 39@87:200x200+100+600@...4 \
    -P 45@87:200x200+200+500@...4 \
    -P 51@87:200x200+300+400@...4 \
