2010-03-08gpiolib: Add support for WM8350 GPIO controllerMark Brown1-0/+1

2009-12-13mfd: Convert WM835x IRQ handling to use a data tableMark Brown1-0/+18
Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

2008-10-14mfd: Add placeholders for WM8350 client devicesMark Brown1-0/+6
In order to avoid merge problems further down the line add placeholders for several of the WM8350 client devices and register them, otherwise the patches adding the client devices will all try to update the same code. Also remove redundant checks for null regulator platform devices while we're at it.

2008-10-14mfd: Add GPIO pin configuration support for WM8350Mark Brown1-0/+10
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.
