Cover letter [DPU PATCH v3 0/2] Remove DPU RSC support
MSM display controller hardware (DPU) has an inbuilt RSC (Resource Coordinator) HW block which can control power resources and bus bandwidth voting based on frame timing parameters without DPU driver intervention.
Downstream driver relies on RSC driver for controlling these resources (via RSC HW block) for better power benefits. Removing RSC device/driver support till the RSC dependencies make their way upstream.
In absence of RSC HW, DPU driver controls these resources currently via a custom implementation for power management. Next, we will work on moving the power resource management using runtime_pm.
Corresponding devicetree binding are also removed.
Details for DPU driver upstreaming:
