From 5ccee4ae8eab957ab6d534283db5bd27703dba03 Mon Sep 17 00:00:00 2001 From: Graeme Gregory Date: Sun, 22 May 2011 21:21:24 +0100 Subject: USB: TWL6025 allow different regulator name The twl6025 uses a different regulator for USB than the 6030 so select the correct regulator name depending on the subclass of device. Since V1 Use features passed via platform data instead of global variable.
