[PATCH 1/2] dt-bindings: Add Qualcomm USB Super-Speed PHY bindings

From: Jorge Ramirez-Ortiz <hidden>
Date: 2018-12-07 09:56:22
Also in: linux-usb, lkml
Subsystem: arm/qualcomm mailing list, open firmware and flattened device tree bindings, the rest, usb subsystem · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Greg Kroah-Hartman

Binding description for Qualcomm's Synopsys 1.0.0 super-speed PHY
controller embedded in QCS404.

Based on Sriharsha Allenki's [off-list ref] original
definitions.

+Qualcomm Synopsys 1.0.0 SS phy controller
+===========================================
+
+Synopsys 1.0.0 ss phy controller supports SS usb connectivity on Qualcomm
+chipsets
+
+Required properties:
+
+- compatible:
+    Value type: <string>
+    Definition: Should contain "qcom,usb-ssphy".
+
+- reg:
+    Value type: <prop-encoded-array>
+    Definition: USB PHY base address and length of the register map.
+
+- #phy-cells:
+    Value type: <u32>
+    Definition: Should be 0. See phy/phy-bindings.txt for details.
+
+- clocks:
+    Value type: <prop-encoded-array>
+    Definition: See clock-bindings.txt section "consumers". List of
+		 three clock specifiers for reference, phy core and
+		 pipe clocks.
+
+- clock-names:
+    Value type: <string>
+    Definition: Names of the clocks in 1-1 correspondence with the "clocks"
+		 property. Must contain "ref", "phy" and "pipe".
+
+- vdd-supply:
+    Value type: <phandle>
+    Definition: phandle to the regulator VDD supply node.
+
+- vdda1p8-supply:
+    Value type: <phandle>
+    Definition: phandle to the regulator 1.8V supply node.
+
+- qcom,vdd-voltage-level:
+    Value type: <prop-array>
+    Definition: This is a list of three integer values <no min max> where
+		 each value corresponding to voltage corner in uV.
+
+Optional child nodes:
+
+- vbus-supply:
+    Value type: <phandle>
+    Definition: phandle to the VBUS supply node.
+
+- resets:
+    Value type: <prop-encoded-array>
+    Definition: See reset.txt section "consumers". PHY reset specifiers
+		 for phy core and COR resets.
+
+- reset-names:
+    Value type: <string>
+    Definition: Names of the resets in 1-1 correspondence with the "resets"
+		 property. Must contain "com" and "phy".
+
+Example:
+
+usb3_phy: phy@78000 {
+	compatible = "qcom,usb-ssphy";
+	reg = <0x78000 0x400>;
+	#phy-cells = <0>;
+	clocks = <&rpmcc RPM_SMD_LN_BB_CLK>,
+		 <&gcc GCC_USB_HS_PHY_CFG_AHB_CLK>,
+		 <&gcc GCC_USB3_PHY_PIPE_CLK>;
+	clock-names = "ref", "phy", "pipe";
+	resets = <&gcc GCC_USB3_PHY_BCR>,
+		 <&gcc GCC_USB3PHY_PHY_BCR>;
+	reset-names = "com", "phy";
+	vdd-supply = <&vreg_l3_1p05>;
+	vdda1p8-supply = <&vreg_l5_1p8>;
+	vbus-supply = <&usb3_vbus_reg>;
+	qcom,vdd-voltage-level = <0 1050000 1050000>;
