* Arm memory group manager for Mali GPU device drivers
Required properties:
- compatible: Must be "arm,physical-memory-group-manager"
An example node:
gpu_physical_memory_group_manager: physical-memory-group-manager {
compatible = "arm,physical-memory-group-manager";
};
It must be referenced by the GPU as well, see physical-memory-group-manager:
gpu: gpu@0x6e000000 {
compatible = "arm,mali-midgard";
reg = <0x0 0x6e000000 0x0 0x200000>;
interrupts = <0 168 4>, <0 168 4>, <0 168 4>;
interrupt-names = "JOB", "MMU", "GPU";
clocks = <&scpi_dvfs 2>;
clock-names = "clk_mali";
system-coherency = <31>;
physical-memory-group-manager = <&gpu_physical_memory_group_manager>;
operating-points = <
/* KHz uV */
50000 820000
>;
};
