2013-03-12Input: wm9712 - fix wrong pen up readingsMarkus Pargmann
Often a reading can be wrong. This patch assures that this is really a pen up event and not a false reading. Based on wm9712: pen up by Teresa Gámez and Christian Hemp.

2013-03-12Input: wm9712 - fix return code for wrong sampleMarkus Pargmann
Instead of interpreting a wrong measurement as pen up, we should try to read again. Based on wm9712: pen up by Teresa Gámez and Christian Hemp.

2011-07-04Input: wm97xx - mark channels which need pen_downWolfram Sang
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.

2011-07-04Input: wm97xx - refactor channel selection in poll_sample()Wolfram Sang
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.
