+ARM Mali Midgard GPU
+====================
+
+Required properties:
+
+- compatible :
+ * Must be one of the following:
+ + "arm,mali-t60x"
+ + "arm,mali-t62x"
+ + "arm,mali-t720"
+ + "arm,mali-t760"
+ + "arm,mali-t820"
+ + "arm,mali-t830"
+ + "arm,mali-t860"
+ + "arm,mali-t880"
+ * And, optionally, one of the vendor specific compatible:
+ + "amlogic,meson-gxm-mali"
Please add a "rockchip,rk3288-mali" as well :-) , as I don't trust that the
generic compatible will be enough for all time and having that already
defined makes fixing the per soc things later a lot easier.
Sure, will do in patch v4.
+
+- 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 : Refer to Documentation/devicetree/bindings/power/opp.txt
+ for details.
So I can simply change that to operating-points-v2. Both
versions can be used in practice but it sounds like
operating-points can just be ignored in this binding's
documentation. Could you please confirm?
Thanks,
Guillaume
