Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
1b799c5cf0
On some devices the "AC" interface ACPI AML code uses the exact same broken logic which is causing the battery code to wrongly report discharging to determine the "AC" state. Specifically the ACPI AML code is checking the charging status bits of the charger-IC rather then the vbus present or power-good status bits. This makes our workaround for devices which wrongly report discharging when plugged into AC while the charge is above the start charging threshold not work on these devices. This commit adds a battery_ac_is_broken flag and when that is set it skips the power_supply_is_system_supplied() check in the workaround fixing this. This flag gets set by a DMI quirk selected by systems where we know the AC AML code is broken in this way *and* the rate_now value can be trusted.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
