The device trees for TQMa6x SOM support variations in - CPU type: imx6dl- or imx6q- - MBa6 I2C bus access: -mba6a (i2c1) or -mba6b (i2c3) (plus the respective common/module include trees) - USBH1 is directly connected to a hub - USBOTG is connected to a separate connector and can act as host/device or full OTG port.
