Subject: dt-bindings: phy: imx8mq-usb: add imx95 tuning support
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=7325e0995f414af1cfa38be965dc47248cb4ec45;p=users%2Fwilly%2Fxarray.git

dt-bindings: phy: imx8mq-usb: add imx95 tuning support

The parameter value of below 3 properties are USB PHY specific. i.MX8MP
and i.MX95 USB PHY has different meanings. This will enlarge parameters
value and add constraints for them.

 - fsl,phy-tx-vref-tune-percent
 - fsl,phy-tx-rise-tune-percent
 - fsl,phy-comp-dis-tune-percent
