Subject: [PATCH net-next v7 0/6] RGMII Internal delay common property

Hello

The RGMII internal delay is a common setting found in most RGMII capable PHY
devices.  It was found that many vendor specific device tree properties exist
to do the same function. This creates a common property to be used for PHY's
that have internal delays for the Rx and Tx paths.

If the internal delay is tunable then the caller needs to pass the internal
delay array and the return will be the index in the array that was found in
the firmware node.

If the internal delay is fixed then the caller only needs to indicate which
delay to return and if the value is defined then the value in the firmware is
returned.

This series contains examples of both a configurable delay and a fixed delay.

Dan Murphy (6):
  dt-bindings: net: Add tx and rx internal delays
  net: phy: Add a helper to return the index for of the internal delay
  dt-bindings: net: Add RGMII internal delay for DP83869
  net: dp83869: Add RGMII internal delay configuration
  dt-bindings: net: dp83822: Add TI dp83822 phy
  net: phy: DP83822: Add ability to advertise Fiber connection
