| * 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 |
| >; |
| }; |
