From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Use devm_reset_control_get_optional_exclusive() instead of devm_reset_control_get_exclusive() to allow the driver to operate on platforms where a reset controller is not present. This change is in preparation for supporting the RZ/T2H SoC, which does not have reset.
