+ARM Mali Midgard GPU
+====================
+
+Required properties:
+
+- compatible :
+  * Must contain one of the following:
+    + "arm,mali-t604"
+    + "arm,mali-t624"
+    + "arm,mali-t628"
+    + "arm,mali-t720"
+    + "arm,mali-t760"
+    + "arm,mali-t820"
+    + "arm,mali-t830"
+    + "arm,mali-t860"
+    + "arm,mali-t880"
+  * which must be preceded by one of the following vendor specifics:
+    + "amlogic,meson-gxm-mali"
+    + "rockchip,rk3288-mali"
+
+- reg : Physical base address of the device and length of the register area.
+
+- interrupts : Contains the three IRQ lines required by Mali Midgard devices.
+
+- interrupt-names : Contains the names of IRQ resources in the order they were
+  provided in the interrupts property. Must contain: "job", "mmu", "gpu".
+
+
+Optional properties:
+
+- clocks : Phandle to clock for the Mali Midgard 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/power/opp.txt
+  for details.
