Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for
the touchscreen use case. By implementing it as an IIO ADC device, we can
make use of resistive-adc-touch and iio-hwmon drivers.
Polled readings are currently not implemented to keep this patch small, so
iio-hwmon will not work out of the box for now.
So far, this driver was tested with a custom version of resistive-adc-touch driver,
since it needs to be extended to make use of Z1 and Z2 channels. The X/Y
are working without additional changes.

With commit 3ba10e37371d ("iio: adis: add burst_max_speed_hz variable"), we
just need to define 'burst_max_speed_hz' and the adis core will take

Typically, in burst mode, the device cannot operate at it's full spi
speed. Hence, the spi transfers for burst mode have to take this into
account. With this change we avoid a potential race with the spi core as
drivers were 'hacking' the device 'max_speed_hz' directly in the
trigger handler.

On an IRQ handler we should not return normal error codes as 'irqreturn_t'
is expected.
This is done by jumping to the 'check_burst32' label where we return
'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this
error path. If we have proper settings to apply burst32, we might just
do the setup now so that the next sample already uses it.

Not all of the parts supported by this driver use single supply.
Hence we add chip_info fields to say what additional supplies exist
and in the case of vref, ensure that is used for the reference voltage
rather than vcc.
One corner case is the ad7091r which has an internal reference that
can be over-driven by an external reference connected on the vref pin.
To handle that force_ext_vref is introduced and set if an optional
vref regulator is present.
Tested using really simple QEMU model and some fixed regulators.
The devm_add_action_or_reset() callback is changed to take the
regulator as it's parameter so we can use one callback for all the
different regulators without having to store pointers to them in
the iio_priv() structure.

This driver supports configuration via device tree and sysfs.
Supported channels for raw infrared light intensity,
raw combined light intensity and illuminance in lux.
The driver additionally supports iio events on lower and
upper thresholds.
This is a very-high sensitivity light-to-digital converter that
transforms light intensity into a digital signal.

However, the change in the mwifiex_pcie_alloc_sleep_cookie_buf()

In some cases we may need to initialize the host1x client first before
registering it. This commit adds a new helper that will do nothing but
the initialization of the data structure.
At the same time, the initialization is removed from the registration
function. Note, however, that for simplicity we explicitly initialize
the client when the host1x_client_register() function is called, as
opposed to the low-level __host1x_client_register() function. This
allows existing callers to remain unchanged.

It's theoretically possible for the runtime PM reference to leak if the
code fails anywhere between the pm_runtime_resume_and_get() and
pm_runtime_put() calls, so make sure to release the runtime PM reference
in that case.
Practically this will never happen because none of the functions will
fail on Tegra, but it's better for the code to be pedantic in case these
assumptions will ever become wrong.

As kvmgt module contains all handling for VFIO/mdev, leaving mdev attribute
groups in gvt module caused dependency issue. Although it was there for possible
other hypervisor usage, that turns out never to be true. So this moves all mdev
handling into kvmgt module completely to resolve dependency issue.
With this fix, no config workaround is required. So revert previous workaround

The platform_set_drvdata() call is only useful if we need to retrieve back
the private information.
Since the driver doesn't do that, it's not useful to have it.
If this is removed, we can also just do a direct return on
devm_gpiochip_add_data(). We don't need to print that this call failed as
there are other ways to log/see this during probe.
