Signed-off-by: Baruch Siach --- This series does not convert the TCSR binding documentation to YAML. As a result, this commit adds new a dt_binding_check warning: /example-0/syscon@1937000: failed to match any schema with compatible: ['qcom,tcsr-ipq 6018', 'syscon', 'simple-mfd'] If that is a blocker to IPQ6018 PWM support, so be it. Patches will wait for someone else to push them further. v8: Add size cell to 'reg' (Rob) v7: Use 'reg' instead of 'offset' (Rob) Drop 'clock-names' and 'assigned-clock*' (Bjorn) Use single cell address/size in example node (Bjorn) Move '#pwm-cells' lower in example node (Bjorn) List 'reg' as required v6: Device node is child of TCSR; remove phandle (Rob Herring) Add assigned-clocks/assigned-clock-rates (Uwe Kleine-König) v5: Use qcom,pwm-regs for phandle instead of direct regs (Bjorn Andersson, Kathiravan T) v4: Update the binding example node as well (Rob Herring's bot) v3: s/qcom,pwm-ipq6018/qcom,ipq6018-pwm/ (Rob Herring) v2: Make #pwm-cells const (Rob Herring) --- .../devicetree/bindings/pwm/ipq-pwm.yaml | 52 +++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 Documentation/devicetree/bindings/pwm/ipq-pwm.yaml diff --git a/Documentation/devicetree/bindings/pwm/ipq-pwm.yaml b/Documentation/devicetree/bindings/pwm/ipq-pwm.yaml new file mode 100644 index 000000000000..96bc63e336bf --- /dev/null +++ b/Documentation/devicetree/bindings/pwm/ipq-pwm.yaml @@ -0,0 +1,52 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pwm/ipq-pwm.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm IPQ6018 PWM controller + +maintainers: + - Baruch Siach + +properties: + "#pwm-cells": + const: 2 + + compatible: + const: qcom,ipq6018-pwm + + reg: + description: Offset of PWM register in the TCSR block. + maxItems: 1 + + clocks: + maxItems: 1 + +required: + - compatible + - reg + - clocks + - "#pwm-cells" + +additionalProperties: false + +examples: + - | + #include + + tcsr: syscon@1937000 { + compatible = "qcom,tcsr-ipq6018", "syscon", "simple-mfd"; + reg = <0x01937000 0x21000>; + #address-cells = <1>; + #size-cells = <1>; + + pwm: pwm@a010 { + compatible = "qcom,ipq6018-pwm"; + reg = <0xa010 0x20>; + clocks = <&gcc GCC_ADSS_PWM_CLK>; + assigned-clocks = <&gcc GCC_ADSS_PWM_CLK>; + assigned-clock-rates = <100000000>; + #pwm-cells = <2>; + }; + };
