Add missing reset deassertion for Aspeed MDIO bus controller. The reset is asserted by the hardware when power-on so the driver only needs to deassert it. To be able to work with the old DT blobs, the reset is optional since it may be deasserted by the bootloader or the previous kernel. V3: - remove reset property from the required list of the device tree bindings - remove "Cc: stable@xxxxxxxxxxxxxxx" from the commit messages - add more description in the commit message of the dt-binding V2: - add reset property in the device tree bindings - add reset assertion in the error path and driver remove Dylan Hung (3): dt-bindings: net: add reset property for aspeed, ast2600-mdio binding net: mdio: add reset control for Aspeed MDIO ARM: dts: aspeed: add reset properties into MDIO nodes .../bindings/net/aspeed,ast2600-mdio.yaml | 5 +++++ arch/arm/boot/dts/aspeed-g6.dtsi | 4 ++++ drivers/net/mdio/mdio-aspeed.c | 15 ++++++++++++++- 3 files changed, 23 insertions(+), 1 deletion(-) -- 2.25.1
