Subject: [PATCH 0/3] net: phy: initialize PHYs via device tree properties

I was trying to configure the Atheros PHY for my board. There are fixups
all over the place, for example to enable the 125MHz clock output in almost
any i.MX architecture. Instead of adding another fixup in architecture
specific code, try to provide a generic way to init the PHY registers.

This patch series tries to pick up the "broadcom,reg-init" and
"marvell,reg-init" device tree properties idea and make it a more generic
"reg-init" which is handled by phy_device instead of a particular phy
driver.

Michael Walle (3):
  dt-bindings: net: phy: Add reg-init property
  net: phy: export __phy_{read|write}_page
  net: phy: Use device tree properties to initialize any PHYs
