Time Synchronization (CPTS) submodule which is present on KeyStone 66AK2HK/E/L/Gx 1G Switch Subsystem provides the same basic functionality as OMAP CPSW CPTS, but with few additional features: - CPTS rftclk selection (reg CPTS_RFTCLK_SEL). This feature is declared to be supported on am437x SoCs also. - CPTS HW_TS_PUSH events which can be generated by external low frequency time stamp channels (66AK2E/L/Gx, am437x) - one Time Stamp Compare (TS_COMP) output which is reused for PTP PPS feature implementation (66AK2E/L/Gx). Hence, This series enables basic CPTS support on Keystone 2 SoCs by resuing current CPSW CPTS driver.
