From mboxrd@z Thu Jan 1 00:00:00 1970 From: Charles Keepax Subject: [PATCH] ASoC: core: If a platform doesn't have an of_node use parent's node Date: Mon, 7 Nov 2016 13:03:17 +0000 Message-ID: <1478523797-22060-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from mx0b-001ae601.pphosted.com (mx0a-001ae601.pphosted.com [67.231.149.25]) by alsa0.perex.cz (Postfix) with ESMTP id 73C0A265D2B for ; Mon, 7 Nov 2016 14:03:06 +0100 (CET) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org To: broonie@kernel.org Cc: alsa-devel@alsa-project.org, patches@opensource.wolfsonmicro.com, lgirdwood@gmail.com List-Id: alsa-devel@alsa-project.org Support was added to allow location of both CPU and CODEC components of a DAI link from their parent's of_node if they did not have an of_node themselves in this commit: commit 3e0aa8d83bf8 ("ASoC: core: If component doesn't have of_node use parent's node instead") However this leaves platforms as something of a special case as the major DAI component that doesn't do this. Since this is useful for MFD devices which often utilise a single device tree entry for the whole device, add support for looking up platforms from the parent's of_node as well.
