Subject: [PATCH net-next v3 0/2] net: phy: mscc: add support for RGMII MAC mode

Hello,

This series adds support for the RGMII MAC mode for the VSC8584 PHY
family and for RGMII_ID modes (Tx and/or Rx).

I decided to drop the custom delay for now. I made some tests and it
seemed to be working quite well. If we find out we really need to lower
the delay, which I doubt, I'll send support for it.

Thanks!
Antoine

Since v2:
  - Dropped support for custom dt bindings.
  - Add the 2ns delay based on the interface mode.

Since v1:
  - The RGMII skew delays are now set based on the PHY interface mode
    being used (RGMII vs ID vs RXID vs TXID).
  - When RGMII is used, the skew delays are set to their default value,
    meaning we do not rely anymore on the bootloader's configuration.
  - Improved the commit messages.
