This rewrites the IXP4xx CF (IDE) libata driver to use the device tree exclusively to look up its resources: - Probe exclusively from the device tree and look up all resources from there. - Allocate a local state container with devres and pass this around in .private_data. - Initialize with struct ata_port_info. - Use the .set_piomode() callback instead of the much wider .set_mode(), we only support PIO after all. - Bump driver version number from 0.2 to 1.0 to reflect this wider change. - Get a handle on the expansion bus syscon regmap to alter the timings on the chip select. - Put in the more elaborate timing adjustment code for PIO0 to PIO4 in 8 and 16bit mode from the downstream OpenWrt patch. The board file initialization path and platform data include is dropped because the board files will be deleted at the same time as this patch is merged. The platform data file is not deleted right now so as not to conflict with the removal of board files. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
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.
