From 7c1b0ec52969e6e2fb5676dfc74eb2770bc4c7b2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 19 Aug 2013 04:33:22 +0900 Subject: [PATCH] ARM: dts: Enable USB hub on Arndale 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.
