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.
