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. v3: - add missing newline in mdio_bus.c v2: - fixed missed rename of "reset" in at803x.c - move initial reset to mdio_device_reset David Bauer (3): dt-bindings: net: add PHY reset controller binding net: phy: add support for reset-controller net: mdio: rename mdio_device reset to reset_gpio Documentation/devicetree/bindings/net/phy.txt | 6 ++++ drivers/net/phy/at803x.c | 2 +- drivers/net/phy/mdio_bus.c | 33 ++++++++++++++++--- drivers/net/phy/mdio_device.c | 13 ++++++-- include/linux/mdio.h | 3 +- 5 files changed, 48 insertions(+), 9 deletions(-) -- 2.21.0
