+ v4.10-rc1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This includes following upstream commits:
+5519da874ad0 net: phy: broadcom: Move bcm54xx_auxctl_{read, write} to common library
+b14995ac2527 net: phy: broadcom: Add BCM54810 PHY entry

+d92ead16be40 net: phy: broadcom: Add support for BCM54612E
+3cf25904fe46 net: phy: broadcom: Update Auxiliary Control Register macros
+
+Other commits were skipped as they depend on other changes like
+ETHTOOL_PHY_DOWNSHIFT & DOWNSHIFT_DEV_DISABLE and new APIs like
+get_sset_count.
+
+One exception was picking new regs from commit d06f78c4232d ("net: phy:
+broadcom: Add support code for downshift/Wirespeed").
