[PATCH v4 2/4] rtc: renesas-rtca3: Add support for multiple reset lines
Posted by Ovidiu Panait 3 months ago
Switch from devm_reset_control_get_shared() to
devm_reset_control_array_get_shared() when retrieving resets.

The RZ/V2H SoC requires two resets for the RTC block instead of one,
so this will allow to handle multiple resets without additional changes.
