The Qualcomm Geni I2C driver currently probes silently which can be
confusing when debugging potential issues. Add a low level (INFO)
print when each I2C controller is successfully initially set-up.

Subject: [PATCH 3/8] pinctrl: msm: Add ability for drivers to supply a
reserved GPIO list
When booting MSM based platforms with Device Tree or some ACPI
implementations, it is possible to provide a list of reserved pins
via the 'gpio-reserved-ranges' and 'gpios' properties respectively.
However some ACPI tables are not populated with this information,
thus it has to come from a knowledgable device driver instead.
Here we provide the MSM common driver with additional support to
parse this informtion and correctly populate the widely used
'valid_mask'.

Subject: [PATCH 4/8] pinctrl: qcom: sdm845: Provide ACPI support
This patch provides basic support for booting with ACPI instead
of the currently supported Device Tree. When doing so there are a
couple of differences which we need to taken into consideration.
Firstly, the SDM850 ACPI tables omit information pertaining to the
4 reserved GPIOs on the platform. If Linux attempts to touch/
initialise any of these lines, the firmware will restart the
platform.
Secondly, when booting with ACPI, it is expected that the firmware
will set-up things like; Regulators, Clocks, Pin Functions, etc in
their ideal configuration. Thus, the possible Pin Functions
available to this platform are not advertised when providing the
higher GPIOD/Pinctrl APIs with pin information.
