+ARM Mali Bifrost GPU
+====================
+
+Required properties:
+
+- compatible :
+ * Since Mali Bifrost GPU model/revision is fully discoverable by reading
+ some determined registers, must contain the following:
+ + "arm,mali-bifrost"
+ * which must be preceded by one of the following vendor specifics:
+ + "amlogic,meson-g12a-mali"
+
+- reg : Physical base address of the device and length of the register area.
+
+- interrupts : Contains the three IRQ lines required by Mali Bifrost devices,
+ in the following defined order.
+
+- interrupt-names : Contains the names of IRQ resources in this exact defined
+ order: "job", "mmu", "gpu".
+
+Optional properties:
+
+- clocks : Phandle to clock for the Mali Bifrost device.
+
+- mali-supply : Phandle to regulator for the Mali device. Refer to
+ Documentation/devicetree/bindings/regulator/regulator.txt for details.
+
+- operating-points-v2 : Refer to Documentation/devicetree/bindings/opp/opp.txt
+ for details.
+
+- resets : Phandle of the GPU reset line.
+
+Vendor-specific bindings
+------------------------
+
+The Mali GPU is integrated very differently from one SoC to
+another. In order to accommodate those differences, you have the option
+to specify one more vendor-specific compatible, among:
+
+- "amlogic,meson-g12a-mali"
+ Required properties:
+ - resets : Should contain phandles of :
+ + GPU reset line
+ + GPU APB glue reset line
+
+Example for a Mali-G31:
+
+gpu@ffa30000 {
+ compatible = "amlogic,meson-g12a-mali", "arm,mali-bifrost";
+ reg = <0xffe40000 0x10000>;
+ interrupts = <GIC_SPI 160 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 161 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 162 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "job", "mmu", "gpu";
+ clocks = <&clk CLKID_MALI>;
+ mali-supply = <&vdd_gpu>;
+ operating-points-v2 = <&gpu_opp_table>;
+ resets = <&reset RESET_DVALIN_CAPB3>, <&reset RESET_DVALIN>;
+};
+
+gpu_opp_table: opp_table0 {
+ compatible = "operating-points-v2";
