Signed-off-by: Yinbo Zhu <zhuyinbo@xxxxxxxxxxx> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- Change in v9: 1. Add all history changlog information. Change in v8: 1. NO change, but other patch in this series of patches has changes. Change in v7: 1. NO change, but other patch in this series of patches has changes. Change in v6: 1. NO change, but other patch in this series of patches has changes. Change in v5: 1. NO change, but other patch in this series of patches has changes. Change in v4: 1. NO change, but other patch in this series of patches has changes. Change in v3: 1. Drop redundant (last) binding from the title. 2. Drop "- |" between ref_100m node and clk node. Change in v2: 1. Drop "Binding" string in the title. 2. Drop entire allOf and move the contents to top level. 3. Change string "refclk_100m" to "ref_100m". .../bindings/clock/loongson,ls2k-clk.yaml | 63 +++++++++++++++++++ MAINTAINERS | 1 + 2 files changed, 64 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/loongson,ls2k-clk.yaml diff --git a/Documentation/devicetree/bindings/clock/loongson,ls2k-clk.yaml b/Documentation/devicetree/bindings/clock/loongson,ls2k-clk.yaml new file mode 100644 index 000000000000..63a59015987e --- /dev/null +++ b/Documentation/devicetree/bindings/clock/loongson,ls2k-clk.yaml @@ -0,0 +1,63 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/clock/loongson,ls2k-clk.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Loongson-2 SoC Clock Control Module + +maintainers: + - Yinbo Zhu <zhuyinbo@xxxxxxxxxxx> + +description: | + Loongson-2 SoC clock control module is an integrated clock controller, which + generates and supplies to all modules. + +properties: + compatible: + enum: + - loongson,ls2k-clk + + reg: + maxItems: 1 + + clocks: + items: + - description: 100m ref + + clock-names: + items: + - const: ref_100m + + '#clock-cells': + const: 1 + description: + The clock consumer should specify the desired clock by having the clock + ID in its "clocks" phandle cell.
