Linux kernel source tree

Andrew Lunn says: ==================== FEC MDIO speedups This patchset gives a number of speedups for MDIO with the FEC. Replacing interrupt driven with polled IO brings a big speedup due to the overheads of interrupts compared to the short time interval. Clocking the bus faster, when the MDIO targets supports it, can double the transfer rate. And suppressing the preamble, if devices support it, makes each transaction faster. By default the MDIO clock remains 2.5MHz and preables are used. But these can now be controlled from the device tree. Since these are generic properties applicable to more than just FEC, these have been added to the generic MDIO binding documentation. v2: readl_poll_timeout() Add patches to set bus frequency and preamble disable v3: Add Reviewed tags uS->us readl_poll_timeout_atomic() Extend DT binding documentation ==================== Acked-by: Fugang Duan <fugang.duan@nxp.com> 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.
