    reset: make (de)assert report success for self-deasserting reset drivers · 21240eb9
    Philipp Zabel authored
    By now there are drivers using shared reset controls and (de)assert
    calls on platforms with self-deasserting reset lines and thus reset
    drivers that do not implement .assert() and .deassert().
    As long as the initial state of the reset line is deasserted, there
    is no reason for a reset_control_assert call to return an error for
    shared reset controls, or for a reset_control_deassert call to return
    an error for either shared or exclusive reset controls: after a call
    to reset_control_deassert the reset line is guaranteed to be deasserted,
    and after a call to reset_control_assert it is valid for the reset
    line to stay deasserted for shared reset controls.
