+Required properties:
+- compatible: "nvidia,<gpu>"
+ Currently recognized values:
+ - nvidia,gk20a
+ - nvidia,gm20b
+ - nvidia,gp10b
+ - nvidia,gv11b
+- reg: Physical base address and length of the controller's registers.
+ Must contain two entries:
+ - first entry for bar0
+ - second entry for bar1
+- 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
