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.
