* Arm priority control manager for Mali GPU device drivers
|
|
Required properties:
|
|
- compatible: Must be "arm,priority-control-manager"
|
|
An example node:
|
|
gpu_priority_control_manager: priority-control-manager {
|
compatible = "arm,priority-control-manager";
|
};
|
|
It must be referenced by the GPU as well, see priority-control-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>;
|
priority-control-manager = <&gpu_priority_control_manager>;
|
operating-points = <
|
/* KHz uV */
|
50000 820000
|
>;
|
};
