The SM8550 SoC uses Synopsis eUSB2 PHY. Add a dt-binding schema for the new driver. Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> --- There will be a binding check warning from Rob's bot because of the tcsr clock bindings missing (dt-bindings/clock/qcom,sm8550-tcsr.h), but that is expected as the header is already merged through Bjorn's clocks tree. The v4 version of this patch was here: https://lore.kernel.org/all/20230202132511.3983095-2-abel.vesa@xxxxxxxxxx/ Changes since v4: * none Changes since v3: * removed blank line, like Rob suggested * dropped quotes and reset description, like Rob suggested * dropped the RPMH_CXO_PAD_CLK clock and the ref_src clock name to match the schema * fixed filenames of the includes in the example (sm8550-gcc and sm8550-tcsr) Changes since v2: * none Changes since v1: * dropped the "ref src" clock * dropped the usb-repeater property .../bindings/phy/qcom,snps-eusb2-phy.yaml | 74 +++++++++++++++++++ 1 file changed, 74 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/qcom,snps-eusb2-phy.yaml diff --git a/Documentation/devicetree/bindings/phy/qcom,snps-eusb2-phy.yaml b/Documentation/devicetree/bindings/phy/qcom,snps-eusb2-phy.yaml new file mode 100644 index 000000000000..de72577e34a4 --- /dev/null +++ b/Documentation/devicetree/bindings/phy/qcom,snps-eusb2-phy.yaml @@ -0,0 +1,74 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/phy/qcom,snps-eusb2-phy.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm SNPS eUSB2 phy controller + +maintainers: + - Abel Vesa <abel.vesa@xxxxxxxxxx> + +description: + eUSB2 controller supports LS/FS/HS usb connectivity on Qualcomm chipsets. + +properties: + compatible: + const: qcom,sm8550-snps-eusb2-phy + + reg: + maxItems: 1 + + "#phy-cells": + const: 0 + + clocks: + items: + - description: ref + + clock-names: + items: + - const: ref + + resets: + maxItems: 1 + + vdd-supply: + description: + Phandle to 0.88V regulator supply to PHY digital circuit. + + vdda12-supply: + description: + Phandle to 1.2V regulator supply to PHY refclk pll block. + +required: + - compatible + - reg + - "#phy-cells" + - clocks + - clock-names + - vdd-supply + - vdda12-supply + - resets + +additionalProperties: false + +examples: + - | + #include <dt-bindings/clock/qcom,sm8550-gcc.h> + #include <dt-bindings/clock/qcom,rpmh.h> + #include <dt-bindings/clock/qcom,sm8550-tcsr.h> + + usb_1_hsphy: phy@88e3000 { + compatible = "qcom,sm8550-snps-eusb2-phy"; + reg = <0x88e3000 0x154>; + #phy-cells = <0>; + + clocks = <&tcsrcc TCSR_USB2_CLKREF_EN>; + clock-names = "ref"; + + vdd-supply = <&vreg_l1e_0p88>; + vdda12-supply = <&vreg_l3e_1p2>; + + resets = <&gcc GCC_QUSB2PHY_PRIM_BCR>; + }; -- 2.34.1
