Add a "linux,pump-express-vbus-max" property which indicates if the Pump Express+ protocol should be used to increase the charging protocol. If this new property is set and a DCP charger is detected then request a higher charging voltage through the Pump Express+ protocol. So far this new property is only used on x86/ACPI (non devicetree) devs, IOW it is not used in actual devicetree files. The devicetree-bindings maintainers have requested properties like these to not be added to the devicetree-bindings, so the new property is deliberately not added to the existing devicetree-bindings. Changes by Hans de Goede: - Port to my bq25890 patch-series + various cleanups - Make behavior configurable through a new "linux,pump-express-vbus-max" device-property - Sleep 1 second before re-checking the Vbus voltage after requesting it to be raised, to ensure that the ADC has time to sampled the new Vbus - Add VBUSV bq25890_tables[] entry and use it in bq25890_get_vbus_voltage() - Tweak commit message Signed-off-by: Yauhen Kharuzhy <jekhor@gmail.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Co-developed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
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.
