-NVIDIA Tegra Graphics Processing Units
-
-Required properties:
-- compatible: "nvidia,<gpu>"
- Currently recognized values:
- - nvidia,gk20a
- - nvidia,gm20b
- - nvidia,gp10b
-- 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
-- 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
- instead of vdd-supply. Currently "nvidia,gp10b" makes use of this.
-
-Optional properties:
-- iommus: A reference to the IOMMU. See ../iommu/iommu.txt for details.
-
-Example for GK20A:
-
- gpu@57000000 {
- compatible = "nvidia,gk20a";
- reg = <0x0 0x57000000 0x0 0x01000000>,

- interrupts = <GIC_SPI 157 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 158 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "stall", "nonstall";
- vdd-supply = <&vdd_gpu>;
- clocks = <&tegra_car TEGRA124_CLK_GPU>,
- <&tegra_car TEGRA124_CLK_PLL_P_OUT5>;
- clock-names = "gpu", "pwr";
- resets = <&tegra_car 184>;
- reset-names = "gpu";
- iommus = <&mc TEGRA_SWGROUP_GPU>;
- };

-

- resets = <&tegra_car 184>;
