Yangbo Lu says: ==================== Support programmable pins for Ocelot PTP driver The Ocelot PTP clock driver had been embedded into ocelot.c driver. It had supported basic gettime64/settime64/adjtime/adjfine functions by now which were used by both Ocelot switch and Felix switch. This patch-set is to move current ptp clock code out of ocelot.c driver maintaining as a single ocelot_ptp.c driver, and to implement 4 programmable pins with only PTP_PF_PEROUT function for now. The PTP_PF_EXTTS function will be supported in the future, and it should be implemented separately for Felix and Ocelot, because of different hardware interrupt implementation in them. Changes for v2: - Put PTP driver under drivers/net/ethernet/mscc/. - Dropped MAINTAINERS patch. Kept original maintaining. - Initialized PTP separately in ocelot/felix platforms. - Supported PPS case in programmable pin. - Supported disabling pin function since deadlock is fixed by Richard. - Returned -EBUSY if not finding pin available. Changes for v3: - Re-sent. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
