Signed-off-by: Daniel Golle --- v2: * dropped unused labels * add 'type: object' declaration for reset-controller found in new ethwarp controller and represented as ti,syscon-reset * rebase on top of "dt-bindings: arm: mediatek: move ethsys controller & convert to DT schema" .../arm/mediatek/mediatek,infracfg.yaml | 1 + .../arm/mediatek/mediatek,mt7988-ethwarp.yaml | 61 +++++++++++++++++++ .../arm/mediatek/mediatek,mt7988-mcusys.yaml | 46 ++++++++++++++ .../arm/mediatek/mediatek,mt7988-xfi-pll.yaml | 49 +++++++++++++++ .../bindings/clock/mediatek,apmixedsys.yaml | 1 + .../bindings/clock/mediatek,ethsys.yaml | 1 + .../bindings/clock/mediatek,topckgen.yaml | 1 + .../bindings/net/pcs/mediatek,sgmiisys.yaml | 2 + 8 files changed, 162 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-ethwarp.yaml create mode 100644 Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-mcusys.yaml create mode 100644 Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-xfi-pll.yaml diff --git a/Documentation/devicetree/bindings/arm/mediatek/mediatek,infracfg.yaml b/Documentation/devicetree/bindings/arm/mediatek/mediatek,infracfg.yaml index ea98043c6ba3d..230b5188a88db 100644 --- a/Documentation/devicetree/bindings/arm/mediatek/mediatek,infracfg.yaml +++ b/Documentation/devicetree/bindings/arm/mediatek/mediatek,infracfg.yaml @@ -30,6 +30,7 @@ properties: - mediatek,mt7629-infracfg - mediatek,mt7981-infracfg - mediatek,mt7986-infracfg + - mediatek,mt7988-infracfg - mediatek,mt8135-infracfg - mediatek,mt8167-infracfg - mediatek,mt8173-infracfg diff --git a/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-ethwarp.yaml b/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-ethwarp.yaml new file mode 100644 index 0000000000000..5b988efe0cb74 --- /dev/null +++ b/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7988-ethwarp.yaml @@ -0,0 +1,61 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/arm/mediatek/mediatek,mt7988-ethwarp.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MediaTek MT7988 ethwarp Controller + +maintainers: + - Daniel Golle + +description: + The Mediatek MT7988 ethwarp controller provides clocks and resets for the + Ethernet related subsystems found the MT7988 SoC. + The reset-controller can be represented using the ti,syscon-reset bindings. + The clock values can be found in . + +properties: + compatible: + items: + - const: mediatek,mt7988-ethwarp + - const: syscon + - const: simple-mfd + + reg: + maxItems: 1 + + reset-controller: + type: object + + '#clock-cells': + const: 1 + +required: + - compatible + - reg + - '#clock-cells' + +additionalProperties: false + +examples: + - | + #include + soc { + #address-cells = <2>;
