We only care about if there is a successful match from the table (or
no match at all), so let's make dmi_check_system return immediately
instead of iterating thorough the whole table.

Make the dmi callback function return 1 then dmi_check_system
will return immediately if we have a successful match.

This patch enables fetching configuration data, which is normally provided
via platform_data, from the device-tree instead.

If the device is configured from device-tree data, the platform_data struct
is not used, and button data needs to be allocated dynamically. Big part of
this patch deals with confining pdata usage to the probe function, to make
this possible.

AGM packets contain valid button bits, too.
This patch refactors packet processing to parse button bits in AGM packets.
However, they aren't actually used or reported.

The point is to more completely process AGM packets,
and prepare for future patches that may actually use AGM packet button bits.

Synaptics touchpads indicate via a capability bit when they perform reduced

Fuzz = 8 was chosen empirically by observing the raw position data

Currently, battery drivers also use poll_sample() provided by the
wm97xx-core but this code always checks if the pen is down. Mark the
channels which really need this (i.e. for the touchscreen) with the
PEN_DOWN bit, and skip the checks otherwise. Now, the battery channels
can always be read.

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.
