Subject: [PATCH] ARM: dts: Enable USB hub on Arndale
Date: Wed, 14 Aug 2013 10:58:34 +0100	[thread overview]
Message-ID: <1376474314-32491-1-git-send-email-broonie@kernel.org> (raw)

From: Mark Brown <broonie@linaro.org>

The Arndale has a SMSC USB3503 connected in hardware only mode like a PHY,
support it using the usb-nop-xceiv binding.

Note that due to a regrettable decision to use a regulator to represent
the reset signal this uses a fixed voltage regulator to do that, there
is a plan to use the reset controller binding once that is merged so it
does not seem worthwhile to fix the usb-nop-xceiv driver at this point.

This doesn't 100% work right now since we don't yet have a solution to
ensure that this gets started after the USB controller but those
modifications are small (or can be done at runtime with module loading).
