Hi Shawn,

In this series, two functions are added for imx6qdl sabreauto board.

- In the 1st patch, the i2c interface gpio expendor max7310 is added
- In the 2nd patch, the USB support is added
- In the 3rd patch, the driver for max7310 is added

The mainline kernel doesn't seem to have a gpio-reset driver/binding
yet.
