iMX6 Sabre Auto DL: Using ECSPI and USB Simultaneously

Hello All,

 

I have an interesting puzzle here. In the imx6dl-sabreauto-ecspi.dts, turning on ecspi requires turning off usbh1 because i2c3 has a pin conflict with ecspi. I was curious if there was any way to reroute the i2c configuration so that both usb and ecspi can be used simultaneously.

 

On the schematic it appears MAX7310_b can be controlled by i2c2 or i2c3. Since i2c3 has the pin conflict how would I migrate over the dts and dtsi code to i2c2? Or is that even possible?

 

 

Thanks,

Jonathon
