Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages; so all explicit
error messages can be removed from the failure code paths.

We no longer need to set up the reset pin for the st1232 in the board
code, but can pass the GPIO number via the platform data to the driver.
This results in a cleaner grouping of the device setup.

We add the possibility to hand over a GPIO number for the reset pin.
This way we can remove existing board code that takes care of it and
group this information properly in the platform data or in the device
tree configuration.

Most semi-mt drivers use the slots in a manual way, but really only
need to treat the finger count manually. With this patch, a semi-mt
driver may use the input-mt core for everything else.

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

Some devices have too few buttons, which it makes it hard to have
a reset combo that won't trigger automatically. As such a
timeout functionality that requires the combination to be held for
a given amount of time before triggering is introduced.
If a key combo is recognized and held for a 'timeout' amount of time,
the system triggers a reset. If the timeout value is omitted the
driver simply ignores the functionality.

NVIDIA's Tegra20 and Tegra30 supports the 16x8 keyboard matrix and T114
support the 11x8 Key matrix.
Add support for defining the maximum row/columns based on SoC through
proper compatibility.

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following

sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
