Qualcomm's APQ8016/MSM8916 USB transceiver controller
- compatible:
Usage: required
Value type: <string>
Definition: Should contain "qcom,usb-8x16-phy".
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: USB PHY base address and length of the register map
- clocks:
Usage: required
Value type: <prop-encoded-array>
Definition: See clock-bindings.txt section "consumers". List of
two clock specifiers for interface and core controller
clocks.
- clock-names:
Usage: required
Value type: <string>
Definition: Must contain "iface" and "core" strings.
- vddcx-supply:
Usage: required
Value type: <phandle>
Definition: phandle to the regulator VDCCX supply node.
- v1p8-supply:
Usage: required
Value type: <phandle>
Definition: phandle to the regulator 1.8V supply node.
- v3p3-supply:
Usage: required
Value type: <phandle>
Definition: phandle to the regulator 3.3V supply node.
- resets:
Usage: required
Value type: <prop-encoded-array>
Definition: See reset.txt section "consumers". PHY reset specifier.
- reset-names:
Usage: required
Value type: <string>
Definition: Must contain "phy" string.
- switch-gpio:
Usage: optional
Value type: <prop-encoded-array>
Definition: Some boards are using Dual SPDT USB Switch, witch is
controlled by GPIO to de/multiplex D+/D- USB lines
between connectors.
Example:
usb_phy: phy@78d9000 {
compatible = "qcom,usb-8x16-phy";
reg = <0x78d9000 0x400>;
vddcx-supply = <&pm8916_s1_corner>;
v1p8-supply = <&pm8916_l7>;
v3p3-supply = <&pm8916_l13>;
clocks = <&gcc GCC_USB_HS_AHB_CLK>,
<&gcc GCC_USB_HS_SYSTEM_CLK>;
clock-names = "iface", "core";
resets = <&gcc GCC_USB2A_PHY_BCR>;
reset-names = "phy";
// D+/D- lines: 1 - Routed to HUB, 0 - Device connector
switch-gpio = <&pm8916_gpios 4 GPIO_ACTIVE_HIGH>;
};
