|
|
+ "rockchip,rk3288-mali"
|
|
+ "rockchip,rk3399-mali"
|
|
|
|
- reg : Physical base address of the device and length of the register area.
|
|
|
|
- interrupts : Contains the three IRQ lines required by Mali Midgard devices.
|
|
|
|
- interrupt-names : Contains the names of IRQ resources in the order they were
|
|
provided in the interrupts property. Must contain: "job", "mmu", "gpu".
|

|
|
|
Optional properties:
|
|
|
|
- clocks : Phandle to clock for the Mali Midgard device.
|
|
|
|
- mali-supply : Phandle to regulator for the Mali device. Refer to
|
|
Documentation/devicetree/bindings/regulator/regulator.txt for details.
|
|
|
|
- operating-points-v2 : Refer to Documentation/devicetree/bindings/opp/opp.txt
