|
|
||
|
|
- reg : Physical base address of the device and length of the register area.
|
||
|
|
|
||
|
|
- interrupts : Contains the three IRQ lines required by Mali Midgard devices.

|
||
|
|
provided in the interrupts property. Must contain: "job", "mmu", "gpu".

|
|
|
||
|
|
|
||
|
|
Optional properties:
|
||

||
|
|
- clocks : Phandle to clock for the Mali Midgard device.
|
||
|
|
