Cover letter [DPU PATCH v2 0/2] Remove DPU RSC support
MSM display controller hardware (DPU) has an inbuilt RSC block which can control power resources and bus bandwidth voting based on frame timing parameters w/o DPU driver intervention. In absence of RSC HW, DPU driver controls these resources.
Downstream driver relies on RSC driver for controlling these resources (via RSC HW block) for better power benefits.
Since, DPU driver can control these resources, removing RSC driver support. Corresponding devicetree binding are also removed.
Details for DPU driver upstreaming:
