Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
e96fd5ce5f
From LPC18xx and LPC43xx User Manuals the GPIO controller consists of the following weakly connected blocks: * GPIO pin interrupt block at 0x40087000, * GPIO GROUP0 interrupt block at 0x40088000, * GPIO GROUP1 interrupt block at 0x40089000, * GPIO port block at 0x400F4000. While all 4 sub-controller blocks have their own I/O addresses, moreover all 3 interrupt blocks are APB0 peripherals and high-speed GPIO block is an AHB slave, according to the hardware manual interrupt controllers and GPIO controller block are seen as a single device, all 4 sub-controllers have the shared reset signal RGU #28 and the same shared clock to access registers CLK_Mx_GPIO on CCU1. The change adds descriptions of the currently missing interrupt controller blocks found on GPIO controller, new added properties are 'reg-names', 'resets', 'interrupt-controller' and '#interrupt-cells', also the example is updated to reflect the changes in device tree binding description.

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.
