Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

The code has the functionality to insert the GPIO lines using
the global GPIO numbers through module parameters.
As we are clearly deprecating the use of global GPIO numbers
look up the GPIO descriptors from the device instead. This
usually falls back to device hardware descriptions using e.g.
device tree or ACPI. This device clearly supports device
tree when used over SPI for example.
For example, this can be supplied in the device tree like so:
wfx@0x01 {
compatible = "silabs,wf200";
reset-gpios = <&gpio0 1>;
wakeup-gpios = <&gpio0 2>;
};

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.
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.
