5de4cd431d Input: wm97xx-core - fix race on PHY init
The chip phy_init() function must be called before the dig_enable() function
but dig_enable() is called when the device is opened and we only call
phy_init() after having reigstered the device, meaning the two can race.
Fix this by doing the phy_init() before we register the input device.

Thanks to Rodolfo Giometti <giometti@enneenne.com> for the report.

6b32ca39d7 Input: wm97xx-core - report a phys for WM97xx touchscreens
phys is displayed in diagnostic output like that from evbug so ensure
that it is set to something.

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.

db7c10e708 Input: wm97xx-core - use IRQF_SAMPLE_RANDOM
The touchscreen interrupt is driven by human input which can reasonably
be used to provide entropy.

d808fbe5b4 Input: wm97xx-core - only schedule interrupt handler if not already scheduled
As well as clarifying the fact that the driver can cope if a second
interrupt occurs before the IRQ work is scheduled this also ensures
that calls to the machine irq_enable() are balanced, making that easier
to implement.  Normally this is redundant due to the interrupt disabling
but some unusal board configurations can trigger it.

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.
