Russell King says: ==================== net: stmmac: simplify axi_blen handling stmmac's axi_blen (burst length) handling is very verbose and unnecessary. Firstly, the burst length register bitfield is the same across all dwmac cores, so we can use common definitions for these bits which platform glue can use. We end up with platform glue: - filling in the axi_blen[] array with the decimal burst lengths, e.g. dwmac-intel.c, etc - decoding a bitmap into burst lengths for this array, e.g. dwmac-dwc-qos-eth.c Other cases read the array from DT, placing it into the axi_blen array, and converting later to the register bitfield. This series removes all this complexity, ultimately ending up with platform glue providing the register value containing the burst length bitfield directly. Where necessary, platform glue calls stmmac_axi_blen_to_mask() to convert a decimal array (e.g. from DT) to the register value. This also means that stmmac_axi_blen_to_mask() can issue a diagnostic message at probe time if the burst length is incorrect. ==================== Link: https://patch.msgid.link/aR2aaDs6rqfu32B-@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.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 reStructuredText 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.
