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.
