mfd: Provide platform data for WM831x GPIO configuration

2011-05-26T17:45:18+00:00

Allow the GPIO mode of WM831x devices to be configured using platform data.
Users may provide a table of GPIO register values in gpio_defaults[]. In
order to allow 0 to be set explicitly out of range values are accepted and
masked off, with a WM831X_GPIO_CONFIGURE define provided to set an out of
range value.

This can be used to configure higher numbered GPIOs or override values set
in OTP for GPIOs configured using OTP.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

2011-05-03T03:26:32+00:00

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: wm831x-ts - move BTN_TOUCH reporting to data transfer
  Input: wm831x-ts - allow IRQ flags to be specified
  Input: wm831x-ts - fix races with IRQ management

Input: wm831x-ts - allow IRQ flags to be specified

2011-04-28T06:12:16+00:00

This allows maximum flexibility for configuring the direct GPIO based
interrupts.

mfd: Add platform data to support multiple WM831x devices per board

2011-03-23T09:42:01+00:00

If a system contains multiple WM831x devices we need to pass a device
number through to the MFD so that we use unique device IDs when we
instantiate child devices. In order to get support for this into 2.6.39
add some platform data to support the configuration, but no implementation
as yet.

mfd: Support configuration of WM831x /IRQ output in CMOS mode

2011-03-23T09:41:44+00:00

Provide platform data allowing the system to set the /IRQ pin into
CMOS mode rather than the default open drain. The default value of
this platform data reflects the default hardware configuration so
there should be no change to existing users.

Input: wm831x - add driver for Wolfson WM831x PMIC touchscreen controllers

2011-01-30T20:32:29+00:00

Some of the WM831x series of PMICs from Wolfson Microelectronics include
a resistive touchscreen controller. Implement support for these controllers
within the input API.

Platform data is supported to allow configuration of system parameters such
as selection between four and five wire touchscreens and for specification
of optional direct to CPU IRQs for sample availability and for pen down.
Use of this feature for at least the data IRQ is strongly recommended.

Thanks to Julien Boibessot for extensive testing and detailed feedback.

mfd: Add WM8326 support

2011-01-14T11:37:39+00:00

The WM8326 is a high performance variant of the WM832x series with
no software visible differences.

mfd: Factor out WM831x I2C I/O from the core driver

2010-10-28T22:30:24+00:00

In preparation for the addition of SPI support for the WM831x move the I2C
specific code into a separate file with a separate Kconfig option so the
I2C support can be excluded from the build.

Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new
symbol.
