ARM Mali Utgard GPU
===================
Required properties:
- compatible
* Must be one of the following:
+ "arm,mali-300"
+ "arm,mali-400"
+ "arm,mali-450"
* And, optionally, one of the vendor specific compatible:
+ allwinner,sun4i-a10-mali
+ allwinner,sun7i-a20-mali
+ amlogic,meson-gxbb-mali
+ amlogic,meson-gxl-mali
+ stericsson,db8500-mali
- reg: Physical base address and length of the GPU registers
- interrupts: an entry for each entry in interrupt-names.
See ../interrupt-controller/interrupts.txt for details.
- interrupt-names:
* ppX: Pixel Processor X interrupt (X from 0 to 7)
* ppmmuX: Pixel Processor X MMU interrupt (X from 0 to 7)
* pp: Pixel Processor broadcast interrupt (mali-450 only)
* gp: Geometry Processor interrupt
* gpmmu: Geometry Processor MMU interrupt
- clocks: an entry for each entry in clock-names
- clock-names:
* bus: bus clock for the GPU
* core: clock driving the GPU itself
Optional properties:
- interrupt-names and interrupts:
* pmu: Power Management Unit interrupt, if implemented in hardware
Vendor-specific bindings
------------------------
The Mali GPU is integrated very differently from one SoC to
another. In order to accomodate those differences, you have the option
to specify one more vendor-specific compatible, among:
- allwinner,sun4i-a10-mali
Required properties:
* resets: phandle to the reset line for the GPU
- allwinner,sun7i-a20-mali
Required properties:
* resets: phandle to the reset line for the GPU
- stericsson,db8500-mali
Required properties:
* interrupt-names and interrupts:
+ combined: combined interrupt of all of the above lines
Example:
mali: gpu@1c40000 {
compatible = "allwinner,sun7i-a20-mali", "arm,mali-400";
reg = <0x01c40000 0x10000>;
interrupts = <GIC_SPI 97 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 99 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 102 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "gp",
"gpmmu",
"pp0",
"ppmmu0",
"pp1",
"ppmmu1",
"pmu";
clocks = <&ccu CLK_BUS_GPU>, <&ccu CLK_GPU>;
clock-names = "bus", "core";
resets = <&ccu RST_BUS_GPU>;
};
