Subject: [PATCH v2 2/3] ARM: dts: omap3-igep0020: Add HS USB Host support
Date: Mon,  7 Oct 2013 11:55:39 +0200	[thread overview]
Message-ID: <1381139740-13495-3-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1381139740-13495-1-git-send-email-javier.martinez@collabora.co.uk>

Add device nodes for the HS USB Host port 1, USB PHY and its
required regulator and also pin mux setup for HS USB1 pins.

Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk>

Changes since v1:
 - Add HST USB port 1 pinmux setup in omap3-igep0020 instead of
   omap3-igep.dtsi since is not used by IGEP COM; suggested by Roger Quadros
