Subject: [PATCH 2/4] mux: allow get mux_control from fwnode if of_node is NULL
Date: Mon, 22 Aug 2022 23:35:15 +0800	[thread overview]
Message-ID: <20220822153517.3747679-3-xu.yang_2@nxp.com> (raw)
In-Reply-To: <20220822153517.3747679-1-xu.yang_2@nxp.com>

Since some devices may link fwnode to dev but doesn't link of_node,
so here we could get mux_control from fwnode again.
