Commit Message

Andrew Halaney July 10, 2023, 8:06 p.m. UTC 
Since this driver only uses devicetree, let's move over to
of_get_phy_mode(). That API has an explicit error return and produces a
phy_interface_t directly instead of an int when representing the phy
mode.

Changes since v1:
    * Convert to using of_get_phy_mode() instead of continuing to use
      device_get_phy_mode() (Andrew Lunn)
