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>; |
