Subject: [PATCH RFC 0/3] reset: Requesting pre-deasserted, auto-reasserting reset controls via devres
Date: Fri, 21 Jun 2024 16:45:01 +0200 [thread overview]
Message-ID: <20240621-reset-get-deasserted-v1-0-94ee76fb7b7d@pengutronix.de> (raw)
There is a recurring pattern of drivers requesting a reset control and
deasserting the reset during probe, followed by registering a reset
assertion via devm_add_action_or_reset().
We can simplify this by providing devm_reset_control_get_*_deasserted()
helpers that return an already deasserted reset control, similarly to
devm_clk_get_enabled().
This doesn't remove a lot of boilerplate at each instance, but there are
quite a few of them now.
regards
Philipp
