Add the device tree binding documentation for the Series AXE GPU used in TI AM62 SoCs. Changes since v3: - Remove oneOf in compatible property - Remove power-supply (not used on AM62) Changes since v2: - Add commit message description - Remove mt8173-gpu support (not currently supported) - Drop quotes from $id and $schema - Remove reg: minItems - Drop _clk suffixes from clock-names - Remove operating-points-v2 property and cooling-cells (not currently used) - Add additionalProperties: false - Remove stray blank line at the end of file Signed-off-by: Sarah Walker <sarah.walker@xxxxxxxxxx> --- .../devicetree/bindings/gpu/img,powervr.yaml | 68 +++++++++++++++++++ MAINTAINERS | 7 ++ 2 files changed, 75 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpu/img,powervr.yaml diff --git a/Documentation/devicetree/bindings/gpu/img,powervr.yaml b/Documentation/devicetree/bindings/gpu/img,powervr.yaml new file mode 100644 index 000000000000..3292a0440465 --- /dev/null +++ b/Documentation/devicetree/bindings/gpu/img,powervr.yaml @@ -0,0 +1,68 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +# Copyright (c) 2022 Imagination Technologies Ltd. +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/gpu/img,powervr.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Imagination Technologies PowerVR GPU + +maintainers: + - Sarah Walker <sarah.walker@xxxxxxxxxx> + +properties: + compatible: + items: + - enum: + - ti,am62-gpu + - const: img,powervr-seriesaxe + + reg: + maxItems: 1 + + clocks: + minItems: 1 + maxItems: 3 + + clock-names: + items: + - const: core + - const: mem + - const: sys + minItems: 1 + + interrupts: + items: + - description: GPU interrupt + + interrupt-names: + items: + - const: gpu + + power-domains: + maxItems: 1 + +required: + - compatible + - reg + - clocks + - clock-names + - interrupts + - interrupt-names + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + #include <dt-bindings/interrupt-controller/arm-gic.h> + + gpu: gpu@fd00000 { + compatible = "ti,am62-gpu", "img,powervr-seriesaxe"; + reg = <0x0fd00000 0x20000>; + power-domains = <&some_pds 187>; + clocks = <&k3_clks 187 0>; + clock-names = "core"; + interrupts = <GIC_SPI 86 IRQ_TYPE_LEVEL_HIGH>; + interrupt-names = "gpu"; + }; diff --git a/MAINTAINERS b/MAINTAINERS index 9852d6bfdb95..0763388b31ef 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -10099,6 +10099,13 @@ IMGTEC IR DECODER DRIVER S: Orphan F: drivers/media/rc/img-ir/ +IMGTEC POWERVR DRM DRIVER +M: Frank Binns <frank.binns@xxxxxxxxxx> +M: Sarah Walker <sarah.walker@xxxxxxxxxx> +M: Donald Robson <donald.robson@xxxxxxxxxx> +S: Supported +F: Documentation/devicetree/bindings/gpu/img,powervr.yaml + IMON SOUNDGRAPH USB IR RECEIVER M: Sean Young <sean@xxxxxxxx> L: linux-media@xxxxxxxxxxxxxxx -- 2.41.0
