Yash Shah says: ==================== Add macb support for SiFive FU540-C000 On FU540, the management IP block is tightly coupled with the Cadence MACB IP block. It manages many of the boundary signals from the MACB IP This patchset controls the tx_clk input signal to the MACB IP. It switches between the local TX clock (125MHz) and PHY TX clocks. This is necessary to toggle between 1Gb and 100/10Mb speeds. Future patches may add support for monitoring or controlling other IP boundary signals. This patchset is mostly based on work done by Wesley Terpstra <wesley@sifive.com> This patchset is based on Linux v5.2-rc1 and tested on HiFive Unleashed board with additional board related patches needed for testing can be found at dev/yashs/ethernet_v3 branch of: https://github.com/yashshah7/riscv-linux.git Change History: V3: - Revert "MACB_SIFIVE_FU540" config changes in Kconfig and driver code. The driver does not depend on SiFive GPIO driver. V2: - Change compatible string from "cdns,fu540-macb" to "sifive,fu540-macb" - Add "MACB_SIFIVE_FU540" in Kconfig to support SiFive FU540 in macb driver. This is needed because on FU540, the macb driver depends on SiFive GPIO driver. - Avoid writing the result of a comparison to a register. - Fix the issue of probe fail on reloading the module reported by: Andreas Schwab <schwab@suse.de> ==================== Signed-off-by: David S.

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.
