Browse source 
Critically, the AST2600 requires ungating the RMII RCLK if e.g. NCSI is
in use.

@ -24,6 +24,13 @@ Optional properties:
- no-hw-checksum: Used to disable HW checksum support. Here for backward
compatibility as the driver now should have correct defaults based on
the SoC.
- clocks: In accordance with the generic clock bindings. Must describe the MAC
IP clock, and optionally an RMII RCLK gate for the AST2500/AST2600. The
required MAC clock must be the first cell.
- clock-names:
- "MACCLK": The MAC IP clock
- "RCLK": Clock gate for the RMII RCLK
