Grygorii Strashko says: ==================== net: ethernet: ti: netcp: update and enable cpts support The Keystone 2 66AK2HK/E/L 1G Ethernet Switch Subsystems contains The Common Platform Time Sync (CPTS) module which is in general compatible with CPTS module found on TI AM3/4/5 SoCs. So, the basic support for Keystone 2 CPTS is available by default, but not documented and has never been enabled inconfig files. The Keystone 2 CPTS module supports also some additional features like time sync reference (RFTCLK) clock selection through CPTS_RFTCLK_SEL register (offset: x08) in CPTS module, which can modelled as multiplexer clock (this was discussed some time ago [1]). This series adds missed binding documentation for Keystone 2 66AK2HK/E/L CPTS module and enables CPTS for TI Keystone 2 66AK2HK/E/L SoCs with possiblity to select CPTS reference clock. Patch 1: adds the CPTS binding documentation. CPTS bindings are defined in the way that allows CPTS properties to be grouped under "cpts" sub-node. It also defines "cpts-refclk-mux" clock for CPTS RFTCLK selection. Patches 2-3: implement CPTS properties grouping under "cpts" sub-node with backward compatibility support. Patch 4: adds support for time sync reference (RFTCLK) clock selection from DT by adding support for "cpts-refclk-mux" multiplexer clock. Patches 5-9: DT CPTS nodes update for TI Keystone 2 66AK2HK/E/L SoCs. Patch 10: enables CPTS for TI Keystone 2 66AK2HK/E/L SoCs. I grouped all patches in one series for better illustration of the changes, but in general Pateches 1-4 are netdev matarieal (first) and other patches are platform specific. Series can be found at: git@git.ti.com:~gragst/ti-linux-kernel/gragsts-ti-linux-kernel.git branch: net-next-k2e-cpts-refclk Changes in v2: - do reverse christmas tree in cpts_of_mux_clk_setup() - add ack from Richard Cochran v1: https://lkml.org/lkml/2019/6/1/77 [1] https://www.spinics.net/lists/netdev/msg408931.html ==================== 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.
