Subject: [PATCH 0/4] net: mediatek: sgmii: add support to change interface parameter while running

When connecting the SGMII interface to a 2.5gbit ethernet phy (e.g. rtl8221
or a SFP slot) the SGMII interface need to change the SGMII connection
parameters (speed, autoneg, duplex, ..) while running to match the phy speed.

Alexander Couzens (4):
  net: mediatek: sgmii: fix powering up the SGMII phy
  net: mediatek: sgmii: ensure the SGMII PHY is powered down on
    configuration
  net: mediatek: sgmii: mtk_pcs_setup_mode_an: don't rely on register
    defaults
  net: mediatek: sgmii: set the speed according to the phy interface in
    AN
