21 - compatible : Should be mali<chip>, replacing digits with x from the back,
22 until malit<Major>xx, ending with arm,mali-midgard, the latter not optional.
23 - reg : Physical base address of the device and length of the register area.
24 - interrupts : Contains the three IRQ lines required by T-6xx devices
25 - interrupt-names : Contains the names of IRQ resources in the order they were
30 - clocks : Phandle to clock for the Mali T-6xx device.
31 - clock-names : Shall be "clk_mali".
32 - mali-supply : Phandle to regulator for the Mali device. Refer to
34 - operating-points : Refer to Documentation/devicetree/bindings/power/opp.txt
36 - jm_config : For T860/T880. Sets job manager configuration. An array containing:
37 	- 1 to override the TIMESTAMP value, 0 otherwise.
38 	- 1 to override clock gate, forcing them to be always on, 0 otherwise.
39 	- 1 to enable job throttle, limiting the number of cores that can be started
41 	- Value between 0 and 63 (including). If job throttle is enabled, this is one
43 - power_model : Sets power model parameters. Note that this model was designed for the Juno
45 	- compatible: Should be arm,mali-simple-power-model
46 	- dynamic-coefficient: Coefficient, in pW/(Hz V^2), which is multiplied
48 	- static-coefficient: Coefficient, in uW/V^3, which is multiplied by
50 	- ts: An array containing coefficients for the temperature scaling
54 	- thermal-zone: A string identifying the thermal zone used for the GPU
55 - system-coherency : Sets the coherency protocol to be used for coherent
58 	- 0  : ACE-Lite
59 	- 1  : ACE
60 	- 31 : No coherency
61 - ipa-model : Sets the IPA model to be used for power management. GPU probe will fail if the
63 	      a gpu-id based model is picked if available, otherwise the default model is used.
64 	- mali-simple-power-model: Default model used on mali
65 - protected-mode-switcher : Phandle to device implemented protected mode switching functionality.
