Jassi Brar says:

====================
Socionext Synquacer NETSEC driver

Changes since v5
	# Removed helper macros
	# Removed 'inline' qualifier
	# Changed multiline empty comment to single line
	# Added 'clock-names' property in DT binding example
	# Ignore 'clock-names' property in driver until f/ws in the wild are
	  upgraded or we support instance that take in more than one clock.
	# Rebased the patchset onto net-next

Changes since v4
        # Fixed ucode indexing as a word, instead of byte
        # Removed redundant clocks, keep only phy rate reference clock
          and expect it to be 'phy_ref_clk'

Changes since v3
        # Discard 'socionext,snq-mdio', and simply use 'mdio' subnode.
        # Use ioremap on ucode region as well, instead of memremap.

Changes since v2
        # Use 'mdio' subnode in DT bindings.
        # Use phy_interface_mode_is_rgmii(), instead of open coding the check.
        # Use readl/b with eeprom_base pointer.
        # Unregister mdio bus upon failure in probe.

Changes since v1
        # Switched from using memremap to ioremap
        # Implemented ndo_do_ioctl callback
        # Defined optional 'dma-coherent' DT property
