Input close or device disable should not interact with the exported
gpiolib functionality. However that's the case. __ad7879_disable()
clears the entire AD7879_REG_CTRL2, while it should just power down
the ADC and its reference.Signed-off-by: Michael Hennerich

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.Signed-off-by: Wolfram Sang
Acked-by: Mark Brown
Signed-off-by: Dmitry Torokhov -
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.Signed-off-by: Wolfram Sang

Depending on the quality of the touch panel, the time for the X-, X+, Y-

Finger touch events or very quick stylus events on low-quality panels
can cause the tsc2007 to read bogus values. Looking at oscilloscope
snapshots, this seems to be caused by the touch event disappearing
during the measurements. These bogus values result in misclicks, where
the X and Y values deviate from the real position.Most of these misclicks can be filtered out by setting a low enough
threshold for the maximum resistance (which is loosely the inverse of
the pressure) allowed to consider a set of values valid. Since this
behaviour is largely dependent on the type and quality of the panel,
this commit introduces the max_rt parameter. The default value is kept
at MAX_12BIT.Signed-off-by: Thierry Reding

This allows maximum flexibility for configuring the direct GPIO based
interrupts.Signed-off-by: Mark Brown
Signed-off-by: Dmitry Torokhov -
If the WM831x pen down and data IRQs run in parallel it is possible for the
data and pen down IRQs to deadlock themselves as one is part way through
disabling its operation while the other is part way through enabling. Fix
this by always disabling the pen down interrupt while data is active and
vice versa. When a changeover is required we disable the IRQ that is to
be stopped then schedule work that will enable the new IRQ.We need to handle the data flow in the data IRQ as the readback from the
device needs to be ordered correctly with the IRQ for robust operation.This also fixes an issue when using the built in IRQs due to enable_irq()
not being valid from interrupt context on an interrupt controller with bus
operations like the built in IRQ controller - this issue may also have
affected other interrupt controllers. We can't rely on having the data
and pen down IRQs available via GPIOs on the CPU on every system.Signed-off-by: Mark Brown
