Hello:

This patch was applied to netdev/net-next.git (refs/heads/master):

On Tue,  2 Feb 2021 15:32:39 +0100 you wrote:
The mdio_bus reset code first de-asserted the reset by allocating with
GPIOD_OUT_LOW, then asserted and de-asserted again. In other words, if
the reset signal defaulted to asserted, there'd be a short "spike"
before the reset.

Here is what happens depending on the pre-existing state of the reset
signal:
Reset (previously asserted):   ~~~|_|~~~~|_______
Reset (previously deasserted): _____|~~~~|_______
                                  ^ ^    ^
                                  A B    C
