-Subject: [PATCH] net: phy: broadcom: Add BCM54810 PHY entry
-
-The BCM54810 PHY requires some semi-unique configuration, which results
-in some additional configuration in addition to the standard config.
-Also, some users of the BCM54810 require the PHY lanes to be swapped.
-Since there is no way to detect this, add a device tree query to see if
-it is applicable.
