0001 Device tree binding documentation for Motorola Mapphone MDM6600 USB PHY
0002
0003 Required properties:
0004 - compatible Must be "motorola,mapphone-mdm6600"
0005 - enable-gpios GPIO to enable the USB PHY
0006 - power-gpios GPIO to power on the device
0007 - reset-gpios GPIO to reset the device
0008 - motorola,mode-gpios Two GPIOs to configure MDM6600 USB start-up mode for
0009 normal mode versus USB flashing mode
0010 - motorola,cmd-gpios Three GPIOs to control the power state of the MDM6600
0011 - motorola,status-gpios Three GPIOs to read the power state of the MDM6600
0012
