Applied, thanks
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.
