Device tree binding documentation for Motorola Mapphone MDM6600 USB PHY
Required properties:
- compatible Must be "motorola,mapphone-mdm6600"
- enable-gpios GPIO to enable the USB PHY
- power-gpios GPIO to power on the device
- reset-gpios GPIO to reset the device
- motorola,mode-gpios Two GPIOs to configure MDM6600 USB start-up mode for
normal mode versus USB flashing mode
- motorola,cmd-gpios Three GPIOs to control the power state of the MDM6600
- motorola,status-gpios Three GPIOs to read the power state of the MDM6600
Example:
usb-phy {
compatible = "motorola,mapphone-mdm6600";
enable-gpios = <&gpio3 31 GPIO_ACTIVE_LOW>;
power-gpios = <&gpio2 22 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio2 17 GPIO_ACTIVE_HIGH>;
motorola,mode-gpios = <&gpio5 20 GPIO_ACTIVE_HIGH>,
<&gpio5 21 GPIO_ACTIVE_HIGH>;
motorola,cmd-gpios = <&gpio4 7 GPIO_ACTIVE_HIGH>,
<&gpio4 8 GPIO_ACTIVE_HIGH>,
<&gpio5 14 GPIO_ACTIVE_HIGH>;
motorola,status-gpios = <&gpio2 20 GPIO_ACTIVE_HIGH>,
<&gpio2 21 GPIO_ACTIVE_HIGH>,
<&gpio2 23 GPIO_ACTIVE_HIGH>;
#phy-cells = <0>;
};
