[PATCH v2 0/3] reset: Requesting pre-deasserted, auto-reasserting reset controls via devres

[Philipp Zabel]

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
