From 3f0d1c67fa20d524fdcb4a7dcda19ed76c59be44 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 9 Aug 2013 11:41:58 +0100 Subject: usb: misc: usb3503: Support operation with no I2C control Refactor so that register writes for configuration are only performed if the device has a regmap provided and also register as a platform driver. This allows the driver to be used to manage GPIO based control of the device.
