We need to stop the timer on driver unbind or probe failures, otherwise
we get UAF/Oops.

Currently, the ID being set to "rmi4_spi" causes this warning:
"SPI driver rmi4_spi has no spi_device_id for syna,rmi4-spi"
Change the ID to rmi4-spi to stop this warning.

The ucb1400 MFD driver and its gpio and touchscreen child
drivers were only used on a few PXA machines that were unused
for a while and are now removed.
Removing these leaves the AC97 support as ALSA specific,
no other drivers are now connected through this interface.

Controllers that report pressure (e.g. ADS7846) use 5 commands and the
correct sequence is READ_X, READ_Y, READ_Z1, READ_Z2, PWRDOWN.
Controllers that don't report pressure (e.g. ADS7845/ADS7843) use only 3
commands and the correct sequence should be READ_X, READ_Y, PWRDOWN. But
the sequence sent was incorrect: READ_X, READ_Y, READ_Z1.
Fix this by setting the third (and last) command to PWRDOWN.

guards
As the guards only apply to suspend and resume, #ifdef CONFIG_PM_SLEEP
would have been a tighter protection. As pm_sleep_ptr() lets the compiler
see the protected ops structure and callbacks but also lets the compiler
remove it as unused code if !CONFIG_PM_SLEEP this allows the #ifdef
guards to be removed, slightly simplifying the resulting code.
--
It seems likely that DEFINE_SIMPLE_DEV_PM_OPS() would work here but
I'd prefer not to make that change unless someone can confirm that the
extra callbacks registered will have no unwanted side effects in this
driver.

As the new pm_sleep_ptr() macro lets the compiler see the code, but
then remove it if !CONFIG_PM_SLEEP it can be used to avoid the need
for #ifdef guards. Use that in the input core to simplify the code
a little. Note pm_sleep_ptr() has not been applied to each callback
in the ops structure because the pm_sleep_ptr() at the usage site
is sufficient.

SET_RUNTIME_DEV_PM_OPS() is deprecated as it requires explicit protection
against unused function warnings. The new combination of pm_ptr()
and RUNTIME_DEV_PM_OPS() allows the compiler to see the functions,
thus suppressing the warning, but still allowing the unused code to be

additional callbacks for suspend and resume and would need

The I2C and SPI PM callbacks were identical (though wrapped in some
bouncing out to the bus specific container of the struct device and
then back again to get the drvdata). As such rather than just moving
these to SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() take the opportunity
to unify the struct dev_pm_ops and use the new EXPORT_SIMPLE_DEV_PM_OPS()
macro so that we can drop the unused suspend and resume callbacks as well
as the structure if !CONFIG_PM_SLEEP without needing to mark the callbacks
__maybe_unused.

The majority of all pxa board files has not been touched in a long time,
and no users have spoken up in favor of keeping them around. This leaves
only support for the platforms that were already converted to DT, as
well as the gumstix and spitz/akita/borzoi machines that work in qemu
and can still be converted to DT later.

Since commit fc7a6209d571 ("bus: Make remove callback return
void") forces bus_type::remove be void-returned, it doesn't
make much sense for any bus based driver implementing remove
callbalk to return non-void to its caller.
As such, change the remove function for Hyper-V VMBus based
drivers to return void.

After initial start-up, the driver triggers ATI (calibration) with
the newly loaded register configuration in place. Next, the driver
polls a register field to ensure ATI completed in a timely fashion
and that the device is ready to sense.
However, communicating with the device over I2C while ATI is under-
way may induce noise in the device and cause ATI to fail. As such,
the vendor recommends not to poll the device during ATI.
To solve this problem, let the device naturally signal to the host
that ATI is complete by way of an interrupt. A completion prevents
the device from successfully probing until this happens.
As an added benefit, initial switch states are now reported in the
interrupt handler at the same time ATI status is checked. As such,
duplicate code that reports initial switch states has been removed
from iqs269_input_init().
The former logic that scaled ATI timeout and filter settling delay
is not carried forward with the new implementation, as it produces
overly conservative delays at the lower clock rate.
Rather, a single timeout that covers both clock rates is used. The
filter settling delay does not happen to be necessary and has been
removed as well.

Polling the device while it transitions from automatic to manual
power mode switching may keep the device from actually finishing
the transition. The process appears to time out depending on the
polling rate and the device's core clock frequency.
This is ultimately unnecessary in the first place; instead it is
sufficient to write the desired mode during initialization, then
disable automatic switching at suspend. This eliminates the need
to ensure the device is prepared for a manual change and removes
the 'suspend_mode' variable.
Similarly, polling the device while it transitions from one mode
to another under manual control may time out as well. This added
step does not appear to be necessary either, so drop it.
