| |
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
