Wolfram Sang c8f205258b Input: wm97xx - refactor channel selection in poll_sample()
The current implementation of poll_sample() has the problem that one of
its arguments, the channel to be selected, differs from wm9713 to other
variants. This parameter gets passed to the (currently unused)
mach-specific functions pre_sample() and post_sample() which thus have
to deal with codec-specific differences. Refactor the routine so that
the argument to poll_sample() is generic for all codecs and do necessary
conversions only in the codec-specific driver. The outcome even uses
less code and removes the non-standard use of the PEN_DOWN bit to mark
the AUX-channels.

Marek Vasut 99fde513f5 Input: wm97xx - add possibility to control the GPIO_STATUS shift
This patch allows tweaking the behaviour of GPIO_STATUS register
shift quirk that's in wm97xx-core. The problem with GPIO_STATUS
register being shifted by one doesn't appear on all hardware it
seems and causes problems with accelerated touchscreen drivers on
Palm hardware. Therefore an accelerated touchscreen driver can select
if the shift is/isn't happening on the hardware.

Mark Brown 34d278534d Input: wm97xx-core - support use as a wakeup source
The WM97xx touch screen controllers can be used to generate a wakeup
event when the system is suspended. Provide a new core API call
wm97xx_set_suspend_mode() allowing machine drivers to enable this. If no
suspend_mode is provided then the touch panel will be powered down when
the system is suspended.

Mark Brown febf1dff11 Input: add support for WM97xx familty touchscreens
Add support for the touchscreen controllers provided by Wolfson
Microelectronics WM97xx series chips in both polled and streaming
modes.

These drivers have been maintained out of tree since 2003. During
that time the driver the primary maintainer was Liam Girdwood and
a number of people have made contributions including Dmitry Baryshkov,
Stanley Cai, Rodolfo Giometti, Russell King, Marc Kleine-Budde,
Ian Molton, Vincent Sanders, Andrew Zabolotny, Graeme Gregory,
Mike Arthur and myself. Apologies to anyone I have omitted.
