Some EtherAVB variants support internal clock delay configuration, which
can add larger delays than the delays that are typically supported by
the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
properties).
Historically, the EtherAVB driver configured these delays based on the
"rgmii-*id" PHY mode. This was wrong, as these are meant solely for the
PHY, not for the MAC. Hence properties were introduced for explicit
configuration of these delays.
Convert the RZ/G2 DTS files from the old to the new scheme:
- Add default "rx-internal-delay-ps" and "tx-internal-delay-ps"
properties to the SoC .dtsi files, to be overridden by board files
where needed,
- Convert board files from "rgmii-*id" PHY modes to "rgmii", adding
the appropriate "rx-internal-delay-ps" and/or "tx-internal-delay-ps"
overrides.
Notes:
- RZ/G2E does not support TX internal delay handling.
