From: Sascha Hauer <s.hauer@pengutronix.de> To: Barebox List <barebox@lists.infradead.org> Subject: [PATCH 07/17] of: implement of_get_stdoutpath() Date: Thu, 6 May 2021 11:28:51 +0200 [thread overview] Message-ID: <20210506092901.25461-8-s.hauer@pengutronix.de> (raw) In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de> For deep probe support it will be useful to have a function to get the node corresponding to the stdoutpath. of_device_is_stdout_path() already has that functionality in it, so make a separate funcion from it.
