From 0e7203933224cbe09b5a9125f55b177b8dd5b1bd Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 10 Oct 2008 15:58:12 +0100 Subject: mfd: Add GPIO pin configuration support for WM8350 The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions. This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so. This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown.
