Subject: [net-next v2 1/4] dt-bindings: net: ftgmac100: Restrict phy-mode and delay properties for AST2600
Create the new compatibles to identify AST2600 MAC0/1 and MAC3/4.
Add conditional schema constraints for Aspeed AST2600 MAC controllers:
- For "aspeed,ast2600-mac01", restrict phy-mode to "rgmii-id" and
"rgmii-rxid", and require rx/tx-internal-delay-ps properties with 45ps
step.
- For "aspeed,ast2600-mac23", require rx/tx-internal-delay-ps properties
with 250ps step.
- Both require the "scu" property.
Other compatible values remain unrestricted.
Because the RGMII delay on AST2600 MAC0/1 is 45ps and its total delay
step is 32, cannot cover 2ns delay for RGMII to meet center. We need
the PHY side enables RX internal delay and the phy_mode must be
"rgmii-id" or "rgmii-rxid".
