From: Roger Quadros Date: Fri, 7 Jun 2013 13:22:48 +0000 (+0530) Subject: ARM: dts: omap5-uevm: Add USB Host support X-Git-Tag: upstream/snapshot3+hdmi~4840^2~4^2~26 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed7f8e8a1c2a40c332f1701ce317077f3cd35e7c;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git ARM: dts: omap5-uevm: Add USB Host support Provide the RESET regulators for the USB PHYs, the USB Host port modes and the PHY devices. Also provide pin multiplexer information for the USB host pins.
