| 2 | |
| 3 | Required properties: |
| 4 | - compatible Must be "motorola,mapphone-mdm6600" |
| 5 | - enable-gpios GPIO to enable the USB PHY |
| 6 | - power-gpios GPIO to power on the device |
| 7 | - reset-gpios GPIO to reset the device |
| 8 | - motorola,mode-gpios Two GPIOs to configure MDM6600 USB start-up mode for |
| 9 | normal mode versus USB flashing mode |
| 10 | - motorola,cmd-gpios Three GPIOs to control the power state of the MDM6600 |
| 11 | - motorola,status-gpios Three GPIOs to read the power state of the MDM6600 |
| 12 | |
| 13 | Example: |
| 14 | |
| 15 | usb-phy { |
| 16 | compatible = "motorola,mapphone-mdm6600"; |
| 17 | enable-gpios = <&gpio3 31 GPIO_ACTIVE_LOW>; |
| 18 | power-gpios = <&gpio2 22 GPIO_ACTIVE_HIGH>; |
| 19 | reset-gpios = <&gpio2 17 GPIO_ACTIVE_HIGH>; |
| 20 | motorola,mode-gpios = <&gpio5 20 GPIO_ACTIVE_HIGH>, |
| 21 | <&gpio5 21 GPIO_ACTIVE_HIGH>; |
| 22 | motorola,cmd-gpios = <&gpio4 7 GPIO_ACTIVE_HIGH>, |
| 23 | <&gpio4 8 GPIO_ACTIVE_HIGH>, |
| 24 | <&gpio5 14 GPIO_ACTIVE_HIGH>; |
| 25 | motorola,status-gpios = <&gpio2 20 GPIO_ACTIVE_HIGH>, |
| 26 | <&gpio2 21 GPIO_ACTIVE_HIGH>, |
| 27 | <&gpio2 23 GPIO_ACTIVE_HIGH>; |
| 28 | #phy-cells = <0>; |
| 29 | }; |
