I was not able to test it on my own, this is a call for testing for the
owners of these platforms. The git version of modetest now fully
supports writeback.

Use libdrm >= 2.4.117, run modetest -ac to determine the writeback
connector, cat /sys/kernel/debug/dri/0/state to determine
spare CRTC and plane, then run something like:

modetest -M msm -a -s 36@85:1024x768 -o test.d -P 79@85:1024x768

where 36 is the Writeback connector id, 85 is CRTC and 79 is the plane.

Then press Enter and check the test.d file for the raw image dump.

Changes since v1:
- Fixed the DPU_CLK_CTRL_WB2 definition

I think this series needs to be re-based as WB_SDM845_MASK is no longer
present in msm-next and 3/4 patches in this series use that.

Quite the contrary: the WB_SDM845_MASK was added in,
which is now merged to msm-next-lumag

Ah okay, I was comparing against msm-next. Let me complete rest of the review checking the other branch.
