Subject: [PATCH 0/3] Expose REFCLK for RMII and enable RMII

From: Ryan Wanner <Ryan.Wanner@...rochip.com>

This set allows the REFCLK property to be exposed as a dt-property to
properly reflect the correct RMII layout. RMII can take an external or
internal provided REFCLK, since this is not SoC dependent but board
dependent this must be exposed as a DT property for the macb driver.

This set also enables RMII mode for the SAMA7 SoCs gigabit mac.

Ryan Wanner (3):
  dt-bindings: net: cdns,macb: Add external REFCLK property
  net: cadence: macb: Expose REFCLK as a device tree property
  net: cadence: macb: Enable RMII for SAMA7 gem
