[PATCH v4 02/14] arm64: dts: imx8mp-var-som-symphony: enable USB support

[Stefano Radaelli <stefano.radaelli21@gmail.com>]

From: Stefano Radaelli <stefano.r@variscite.com>

Enable the USB controllers on the Symphony carrier board.

Add the PTN5150 Type-C controller for USB role switching, enable the USB3
PHYs and controllers, configure the I2C bus used by the Type-C
controller, and set the first USB port in OTG mode and the second port
in host mode.

v3->v4:
 - Fixed USB irq edge type

v2->v3:
 - 

v1->v2:
 - Update PTN5150 interrupt trigger type
