Subject: [PATCH v3 0/3] net: add reset-controller driven PHY reset

This patchset adds support for a PHY reset driven by a reset-controller.
Currently, only GPIO driven resets are supported by the PHY subsystem.
It also renames the reset-gpio from 'reset' to 'reset_gpio' to
better differentiate between resets wired to a GPIO and resets wired to
a reset-controller driven pin.

Some systems have the PHY reset-line wired to a pin controlled by a
reset-controller (eg. some Atheros AR9132 based boards). In case the
bootloader asserts reset before loading the kernel, we currently do not
have a clean way of deasserting reset to probe the PHY.

 - add missing newline in mdio_bus.c

 - fixed missed rename of "reset" in at803x.c
 - move initial reset to mdio_device_reset
