Subject: [PATCH 0/6] net: ethernet: ti: cpts: update and enable support on keystone 2 socs

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.

Note. This series based on top of  preparation series
      "[PATCH v2 00/13] net: ethernet: ti: cpts: update and fixes"

Tested on am437x-idk, am57xx-evm, 66AK2HK, 66AK2E, 66AK2G
Tests:
   server: ptp4l -E -2 -H -i eth0  -l 6 -m -q -p /dev/ptp0
   client:  ptp4l -E -2 -H -i eth0  -l 6 -m -q -p /dev/ptp0 -s

   testptp -g && sleep X && testptp -g

   testptp -c
   testptp -g
   testptp -s
   testptp -k 25
   testptp -e 3

   testptp -P 1 && .ppstest /dev/pps0
