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.

Commit 0b950d3 (Input: tsc2005 - add open/close) introduced a

cancel_delayed_work_sync() with mutex held, and the work also needs the

Introduce open and close methods for the input device to keep the device
powered down when it is not in use. Also rework interaction between
interrupt thread and starting/shutting off/resetting the device: instead
of taking a mutex in the intterrupt thread and elsewhere disable interrupts
before transitioning the device in a new state.
The ESD handling is also separated from the IRQ thread; we poll regularly
at a given interval and simply skip reads if we see that valid interrupt
happened not so long ago. This allows us not cancel and reschedule ESD
work from interrupt context all the time.

Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.
This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.
A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common

in the driver. This patch moves all tracking event handling over to

This patch introduces support for Sitronix ST1232 integrated capacitive
touchscreen with LCD module. The touchscreen is multitouch capable and
can report coordinates of up to two contact points.

I've recently got my hands on a LG Flatron T1710B touchscreen.
As other LG products, this seems to use the ITM panel.

The kcalloc call for the object table is using sizeof(struct qt602240_data)
when it should be using sizeof(struct qt6602240_object), resulting in a larger
allocation than is required.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: appletouch - remove extra KERN_DEBUG use from dprintk
Input: bu21013_ts - fix null dereference in error handling
Input: ad7879 - prevent invalid finger data reports
Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.
The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.
Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.
We also reject samples where pressure is greater than pressure_max.

input merge)
Instead of using asynchronous SPI API and then spinning waiting for SPI
transfer to complete when disabling the device, let's use threaded IRQ
model and spi_sync().
