Subject: [PATCH 0/3] gpio: deprecate and track the removal of the GPIOD_FLAGS_BIT_NONEXCLUSIVE flag
Date: Mon, 31 Mar 2025 11:00:08 +0200 [thread overview]
Message-ID: <20250331-gpio-todo-remove-nonexclusive-v1-0-25f72675f304@linaro.org> (raw)
This feature is another pet-peeve of mine. It's a hack that people
started using and now it's in all kinds of drivers. It doesn't really
explain what it actually does, and it implements it badly.
Let's deprecate it officially, add it to MAINTAINERS keywords so that it
pops up on our radars when used again, add a task to track it and I plan
to use the power sequencing subsystem to handle the cases where
non-exclusive access to GPIOs is required.
