+- reg: Physical base addresses and lengths of the register areas
+- reg-names: Names for the register areas. The "hub" and "core0"
+ register areas are always required. The "gca" register area
+ is required if the GCA cache controller is present. The
+ "bridge" register area is required if an external reset
+ controller is not present.
+- interrupts: The interrupt numbers. The first interrupt is for the hub,
+ while the following interrupts are separate interrupt lines
+ for the cores (if they don't share the hub's interrupt).
+ See bindings/interrupt-controller/interrupts.txt
+
+Optional properties:
+- clocks: The core clock the unit runs on
+- resets: The reset line for v3d, if not using a mapping of the bridge

+- reg: Physical base address and length of the controller's registers.

+- interrupts: Must contain an entry for each entry in interrupt-names.
+ See ../interrupt-controller/interrupts.txt for details.
+- interrupt-names: Must include the following entries:
+ - stall
+ - nonstall
+- vdd-supply: regulator for supply voltage. Only required for GPUs not using
+ power domains.
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - gpu
+ - pwr
+If the compatible string is "nvidia,gm20b", then the following clock
+is also required:
+ - ref
+If the compatible string is "nvidia,gv11b", then the following clock is also
+required:
+ - fuse
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - gpu
+- power-domains: GPUs that make use of power domains can define this property
