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

When use lpuart with DMA mode as wake up source, it still switch to cpu mode in .suspend() that enable cpu interrupts RIE and ILIE as wakeup source. Enable the wakeup irq bits in .suspend_noirq() and disable the wakeup irq bits in .resume_noirq(). For DMA mode, after system resume back, it needs to setup DMA again, if DMA setup is failed, it switchs to CPU mode. .resume() will share the HW setup code with .startup(), so abstract the same code to the api like lpuartx_hw_setup().

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.
