[RFT PATCH 0/3] Add missing CX_MEM/DBGC GPU regions for SM6115/QCM2290

[Konrad Dybcio]

These regions were previously left undescribed, fix that.

Compile-tested only, the driver shouldn't break though.

[PATCH RFT 1/3] dt-bindings: display/msm/gpu: Straighten out reg-names on A619L/610/702

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

These GPUs have physically have the same regions as the base case
("main" + "cx_mem" + "cx_dbgc"). Remove the specific override.

[PATCH RFT 2/3] arm64: dts: qcom: agatti: Add CX_MEM/DBGC GPU regions

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Describe the GPU register regions, with the former existing but not
being used much if at all on this silicon, and the latter containing
various debugging levers generally related to dumping the state of
the IP upon a crash.
