> 主题: [RESEND PATCH] phy: phy-imx8mq-usb: Add support for i.MX95 USB3 PHY
> 
> Add initial support for i.MX95 USB.30 PHY, which is similar to the i.MX8MQ and
> i.MX8MP USB PHY.
> 
> The i.MX95 USB3 PHY has a Type-C Assist block (TCA) consisting of two
> functional blocks (XBar assist and VBus assist) and is documented in the i.MX95
> RM Chapter 163.3.8 Type-C assist (TCA) block.
> 
> Instead of relying on an external MUX for Type-C plug orientation the XBar can
> handle the flip internally.
> 
> Add initial support for i.MX95 by:
>  - allowing the driver to be enabled i.MX95
>  - resetting the XBar
>  - configuring the TCA in System Configuration mode (which was determined
>    to be necessary to enable the PHY in device-mode)
> 
> Follow-on support will need to be added to steer the XBar based on either board
> design (if only one pair is brought out) or if used with a Type-C controller.
