This series adds support for USB phy tuning parameters, which are
required for meeting USB certification and EMI qualification.

Patch 1/2 adds the required properties to the fsl,imx8mq-usb-phy
devicetree binding.

Patch 2/2 adds the phy tuning parameters to the phy-fsl-imx8mp driver.
This patch is ported and cleaned up from the downstream Freescale vendor
tree.

Best regards,
Johannes

Changelog:

  v1 -> v2: worked in review from Krzysztof and Rob, thanks for your
  review:
   - extract more useful descriptions of the properties from the
     datasheet
   - use unit postfixes for the device tree properties to facilitate
     porting in the future
   - add more information about some of the properties (thanks to Li Jun
     for clarification)
   - adjust parsing of the devicetree properties in the driver to scale
     to the proper register values
