Applied 1/4 and 2/4, dts patches need to go via SoC maintainer. thanks, -srini
v6: no changes, based on kernel 5.19-rc1 v5: sync with the series: https://patchwork.kernel.org/project/linux-mediatek/list/?series=640196 1. change title suggested by Krzysztof; 2. No need drop 'reviewed-by Rob' suggested by Krzysztof 3. add maintainer Lala who maintain efuse driver now; v4: fix duplicated unit-address in example; drop reviewed-by Rob, due to changes; v3: add reviewed-by Rob v2: 1. remove description of subnodes which is covered by nvmem.yaml suggested by Rob 2. change the example which is commoner than mt8173's --- .../bindings/nvmem/mediatek,efuse.yaml | 87 +++++++++++++++++++ .../devicetree/bindings/nvmem/mtk-efuse.txt | 43 --------- 2 files changed, 87 insertions(+), 43 deletions(-) create mode 100644 Documentation/devicetree/bindings/nvmem/mediatek,efuse.yaml delete mode 100644 Documentation/devicetree/bindings/nvmem/mtk-efuse.txt diff --git a/Documentation/devicetree/bindings/nvmem/mediatek,efuse.yaml b/Documentation/devicetree/bindings/nvmem/mediatek,efuse.yaml new file mode 100644 index 000000000000..f6e01ddb7499 --- /dev/null +++ b/Documentation/devicetree/bindings/nvmem/mediatek,efuse.yaml @@ -0,0 +1,87 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/nvmem/mediatek,efuse.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MediaTek efuse + +description: | + MediaTek's efuse is used for storing calibration data, it can be accessed + on ARM devices usiong I/O mapped memory. + +maintainers: + - Andrew-CT Chen <andrew-ct.chen@xxxxxxxxxxxx> + - Lala Lin <lala.lin@xxxxxxxxxxxx> + +allOf: + - $ref: "nvmem.yaml#" + +properties: + $nodename: + pattern: "^efuse@[0-9a-f]+$" + + compatible: + oneOf: + - items: + - enum: + - mediatek,mt7622-efuse + - mediatek,mt7623-efuse + - mediatek,mt8173-efuse + - mediatek,mt8192-efuse + - mediatek,mt8195-efuse + - mediatek,mt8516-efuse + - const: mediatek,efuse + - const: mediatek,mt8173-efuse + deprecated: true + + reg: + maxItems: 1 + +required: + - compatible + - reg + +unevaluatedProperties: false + +examples: + - | + efuse@11c10000 { + compatible = "mediatek,mt8195-efuse", "mediatek,efuse"; + reg = <0x11c10000 0x1000>; + #address-cells = <1>; + #size-cells = <1>; + + u3_tx_imp_p0: usb3-tx-imp@184,1 { + reg = <0x184 0x1>; + bits = <0 5>; + }; + u3_rx_imp_p0: usb3-rx-imp@184,2 { + reg = <0x184 0x2>; + bits = <5 5>; + }; + u3_intr_p0: usb3-intr@185 { + reg = <0x185 0x1>; + bits = <2 6>; + }; + comb_tx_imp_p1: usb3-tx-imp@186,1 { + reg = <0x186 0x1>; + bits = <0 5>; + }; + comb_rx_imp_p1: usb3-rx-imp@186,2 { + reg = <0x186 0x2>; + bits = <5 5>; + }; + comb_intr_p1: usb3-intr@187 { + reg = <0x187 0x1>; + bits = <2 6>; + }; + u2_intr_p0: usb2-intr-p0@188,1 { + reg = <0x188 0x1>; + bits = <0 5>; + }; + u2_intr_p1: usb2-intr-p1@188,2 { + reg = <0x188 0x2>; + bits = <5 5>; + }; + }; diff --git a/Documentation/devicetree/bindings/nvmem/mtk-efuse.txt b/Documentation/devicetree/bindings/nvmem/mtk-efuse.txt deleted file mode 100644 index 39d529599444..000000000000 --- a/Documentation/devicetree/bindings/nvmem/mtk-efuse.txt +++ /dev/null @@ -1,43 +0,0 @@ -= Mediatek MTK-EFUSE device tree bindings = - -This binding is intended to represent MTK-EFUSE which is found in most Mediatek SOCs. - -Required properties: -- compatible: should be - "mediatek,mt7622-efuse", "mediatek,efuse": for MT7622 - "mediatek,mt7623-efuse", "mediatek,efuse": for MT7623 - "mediatek,mt8173-efuse" or "mediatek,efuse": for MT8173 - "mediatek,mt8192-efuse", "mediatek,efuse": for MT8192 - "mediatek,mt8195-efuse", "mediatek,efuse": for MT8195 - "mediatek,mt8516-efuse", "mediatek,efuse": for MT8516 -- reg: Should contain registers location and length -- bits: contain the bits range by offset and size - -= Data cells = -Are child nodes of MTK-EFUSE, bindings of which as described in -bindings/nvmem/nvmem.txt - -Example: - - efuse: efuse@10206000 { - compatible = "mediatek,mt8173-efuse"; - reg = <0 0x10206000 0 0x1000>; - #address-cells = <1>; - #size-cells = <1>; - - /* Data cells */ - thermal_calibration: calib@528 { - reg = <0x528 0xc>; - }; - }; - -= Data consumers = -Are device nodes which consume nvmem data cells. - -For example: - - thermal { - ... - nvmem-cells = <&thermal_calibration>; - nvmem-cell-names = "calibration"; - };
