From 1bca748cccec1c7f30b4424882de965100744432 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 17 Feb 2010 18:45:26 +0000 Subject: [PATCH] gpiolib: Force wm831x GPIOs into GPIO mode when requested This is the chip default but it's possible the bootloader or OTP will have been configured to a different mode (eg, to provide feedback during startup).
