Subject: [PATCH] ARM: dts: omap3-beagle-xm: Add USB Host support for Rev Ax/Bx
Date: Mon, 15 Apr 2013 15:35:06 +0300	[thread overview]
Message-ID: <1366029306-1824-1-git-send-email-rogerq@ti.com> (raw)

Provide RESET and Power regulators for the USB PHY,
the USB Host port mode and the PHY device.

Also provide pin multiplexer information for USB host
pins.

This will not work for Rev Cx boards because of reversed logic
for USB_POWER_Enable.
