Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

acpi_get_and_request_gpiod() does not take a gpio_lookup_flags argument specifying that the pins direction should be initialized to a specific value. This means that in some cases the pins might be left in input mode, causing the gpiod_set() calls made to enable the clk / regulator to not work. One example of this problem is the clk-enable GPIO for the ov01a1s sensor on a Dell Latitude 9420 being left in input mode causing the clk to never get enabled. Explicitly set the direction of the pins to output to fix this. Fixes: 5de691bf ("platform/x86: Add intel_skl_int3472 driver") Signed-off-by:Hans de Goede <hdegoede@redhat.com> Reviewed-by:
