Hello,

This series slightly extends the devicetree binding and driver for the
FTGMAC100 to describe an optional RMII RCLK gate in the clocks property.
Currently it's necessary for the kernel to ungate RCLK on the AST2600 in NCSI
configurations as u-boot does not yet support NCSI (which uses the RMII).

Please review!

Andrew

RMII as in Reduced MII or Reverse MII in that context?

Reduced MII ( https://en.wikipedia.org/wiki/NC-SI#Hardware_interface )
