22f57707fa pinctrl: intel: allow independent COMPILE_TEST
Now that we have completed the transition to standard ACPI helpers for the
entire Intel pinctrl tree, we can detach COMPILE_TEST from ACPI dependency.

a35c62ba7a pinctrl: intel: Refactor intel_pinctrl_get_soc_data()
Refactor intel_pinctrl_get_soc_data() to drop initial assignment
of the data variable. It's only used in ACPI case and instead
we may always assign it there as the ACPI ID table has the terminator
entry that has driver data set to NULL.

6217728b38 pinctrl: intel: Move default strength assignment to a switch-case
iWhen ->pin_config_set() is called from the GPIO library (assumed
GpioIo() ACPI resource), the argument can be 1, when, for example,
PullDefault is provided. In such case we supply sane default in
the driver. Move that default assingment to a switch-case, so
it will be consolidated in one place.

b10a74b5c0 pinctrl: intel: Provide Intel pin control wide PM ops structure
With the help of EXPORT_NS_GPL_DEV_PM_OPS() and
NOIRQ_SYSTEM_SLEEP_PM_OPS() we may convert PM ops functions to become
static. This also takes into account the PM configuration options such
as CONFIG_PM and CONFIG_PM_SLEEP. Hence the first step is to provide
a generic PM ops structure that can be used by drivers directly.

e0ba7366a6 pinctrl: cherryview: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

d338655215 pinctrl: cherryview: Avoid duplicated I/O
In some cases we already read the value from the register followed
by a reading of it again for other purposes, but the both reads
are under the lock and bits we are insterested in are not going
to change (they are not volatile from HW perspective). Hence, no
need to read the same register twice.

3013c7f778 pinctrl: denverton: Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE()
As Krzysztof pointed out the better is to use MODULE_DEVICE_TABLE()
as it will be consistent with the content of the real ID table of
the platform devices.

Improve intel_config_set_pull() implementation in Intel pinctrl driver by:

- Reducing scope of spinlock by moving unneeded operations out of it.
- Utilizing temporary variables for common operations.
- Limiting IO operations to positive cases.
