Rasmus Villemoes says: ==================== net: dsa: microchip: fix writes to phy registers >= 0x10 Patch 1 is just a simplification, technically unrelated to the other two patches. But it would be a bit inconsistent to have the new ksz_prmw32() introduced in patch 2 use ksz_rmw32() while leaving ksz_prmw8() as-is. The actual fix is of course patch 3. I can definitely see some weird behaviour on our ksz9567 when writing to phy registers 0x1e and 0x1f (with phytool from userspace), though it does not seem that the effect is always to write zeroes to the buddy register as the errata sheet says would be the case. In our case, the switch is connected via i2c; I hope somebody with other switches and/or the SPI variants can test this. ==================== Link: https://lore.kernel.org/r/20230620113855.733526-1-linux@rasmusvillemoes.dk 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 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.
