Fork of reMarkable kernel https://github.com/reMarkable/linux

The DMA (NHI) port of a switch provides access to the NVM of the host controller (and devices starting from Intel Alpine Ridge). The NVM contains also more complete DROM for the root switch including vendor and device identification strings. This will look for the DMA port capability for each switch and if found populates sw->dma_port. We then teach tb_drom_read() to read the DROM information from NVM if available for the root switch. The DMA port capability also supports upgrading the NVM for both host controller and devices which will be added in subsequent patches. This code is based on the work done by Amir Levy and Michael Jamet.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
