-Vivante GPU core devices
-========================
-
-Required properties:
-- compatible: Should be "vivante,gc"
-  A more specific compatible is not needed, as the cores contain chip
-  identification registers at fixed locations, which provide all the
-  necessary information to the driver.
-- reg: should be register base and length as documented in the
-  datasheet
-- interrupts: Should contain the cores interrupt line
-- clocks: should contain one clock for entry in clock-names
-  see Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names:
-   - "bus":    AXI/master interface clock
-   - "reg":    AHB/slave interface clock
-               (only required if GPU can gate slave interface independently)
-   - "core":   GPU core clock
-   - "shader": Shader clock (only required if GPU has feature PIPE_3D)
-
-Optional properties:
-- power-domains: a power domain consumer specifier according to
-  Documentation/devicetree/bindings/power/power_domain.txt
-
-example:
-
-gpu_3d: gpu@130000 {
-       compatible = "vivante,gc";
-       reg = <0x00130000 0x4000>;
-       interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
-       clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,
-                <&clks IMX6QDL_CLK_GPU3D_CORE>,
-                <&clks IMX6QDL_CLK_GPU3D_SHADER>;
-       clock-names = "bus", "core", "shader";
-       power-domains = <&gpc 1>;
-};
