Re: [PATCH v4 06/12] drm/msm/dpu: Add SM6350 support

Add SM6350 support to the DPU1 driver to enable display output.

It's worth noting that one entry dpu_qos_lut_entry was trimmed off:

{.fl = 0, .lut = 0x0011223344556677 },

due to the fact that newer SoCs dropped the .fl (fill level)-based
logic and don't provide real values, resulting in all entries but
the last one being unused.

I think that the commit message is misleading. The DPU driver uses 
fill-level logic. It doesn't yet support selecting between portrait and 
landscape LUT settings (for danger and safe LUTs) and it doesn't provide 
full support for qseed/non-qseed usescases (for QoS LUT).
