We cannot enforce a default, since we can't know for sure\nthat all our users will use it that way (even though the majority\nprobably will). This is why you also have those nodes populated but\ndisabled for the uart for example in the pine64 DTS.\n\nBut in our case, there's not much to populate :)\n\nMaxime","headers":{"Return-Path":"","X-Original-To":"incoming-imx@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming-imx@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=lists.infradead.org\n\t(client-ip=65.50.211.133; helo=bombadil.infradead.org;\n\tenvelope-from=linux-arm-kernel-bounces+incoming-imx=patchwork.ozlabs.org@lists.infradead.org;\n\treceiver=)","ozlabs.org; dkim=pass (2048-bit key;\n\tunprotected) header.d=lists.infradead.org\n\theader.i=@lists.infradead.org\n\theader.b=\"bNadPsCr\"; dkim-atps=neutral"],"Received":["from bombadil.infradead.org (bombadil.infradead.org\n\t[65.50.211.133])\n\t(using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256\n\tbits)) (No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3xj7px05Hgz9sMN\n\tfor ;\n\tThu, 31 Aug 2017 00:55:36 +1000 (AEST)","from localhost ([127.0.0.1] helo=bombadil.infradead.org)\n\tby bombadil.infradead.org with esmtp (Exim 4.87 #1 (Red Hat Linux))\n\tid 1dn4Ou-00009a-Sr; Wed, 30 Aug 2017 14:55:28 +0000","from mail.free-electrons.com ([62.4.15.54])\n\tby bombadil.infradead.org with esmtp (Exim 4.87 #1 (Red Hat Linux))\n\tid 1dn4Ih-0003s1-3m for linux-arm-kernel@lists.infradead.org;\n\tWed, 30 Aug 2017 14:49:09 +0000","by mail.free-electrons.com (Postfix, from userid 110)\n\tid A155F208EA; Wed, 30 Aug 2017 16:48:42 +0200 (CEST)","from localhost (LStLambert-657-1-97-87.w90-63.abo.wanadoo.fr\n\t[90.63.216.87])\n\tby mail.free-electrons.com (Postfix) with ESMTPSA id 7513620789;\n\tWed, 30 Aug 2017 16:48:42 +0200 (CEST)"],"DKIM-Signature":"v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed;\n\td=lists.infradead.org; s=bombadil.20170209; h=Sender:Content-Type:Cc:\n\tList-Subscribe:List-Help:List-Post:List-Archive:List-Unsubscribe:List-Id:\n\tIn-Reply-To:MIME-Version:References:Message-ID:Subject:To:From:Date:Reply-To:\n\tContent-Transfer-Encoding:Content-ID:Content-Description:Resent-Date:\n\tResent-From:Resent-Sender:Resent-To:Resent-Cc:Resent-Message-ID:List-Owner;\n\tbh=bgiXKIQCdr+vyc3/hxtM4o6MZb2lS/NivUD83X5vp5I=;\n\tb=bNadPsCry9OYN7+rY/fXaU36W\n\t0UeX4n/JTcEL9ks0ikeNM0hDzesuI4ejeJNjDujS/KmXy6lKNfd+LV/0REShwybUFyzffvHEclQ3w\n\tVbVdutbZHTRgwsTbdcSkPPgDLzJecHOyJqskSk7kh/Z+QZ82XlBbzyur2YDaJbcDwZv7KSnxTdSIA\n\tbvgdFhtQS8zxtPCU8+A8dLV6VchjSTcy1mTMiybFjz2k6l54kkwLvdIMeb1MJA+kPPmw+rO+ByOy2\n\tye+P3KuBiW/Di8eG+kEdLiGCmWI5dDIijjY8MdxaE2YxrH+FvbVYuKLwDQnsvLHg+ZsOXJyIBo+ST\n\tEhQjQd5ug==;","X-Spam-Checker-Version":"SpamAssassin 3.4.0 (2014-02-07) on\n\tmail.free-electrons.com","X-Spam-Level":"","X-Spam-Status":"No, score=-1.0 required=5.0 tests=ALL_TRUSTED,SHORTCIRCUIT,\n\tURIBL_BLOCKED shortcircuit=ham autolearn=disabled version=3.4.0","Date":"Wed, 30 Aug 2017 16:48:43 +0200","From":"Maxime Ripard ","To":"Stefan =?iso-8859-1?q?Br=FCns?= ","Subject":"Re: [RESEND PATCH 2/2] arm64: allwinner: pine64: Enable spi0/spi1","Message-ID":"<20170830144843.zyqmf3awivzfqtbf@flea.lan>","References":"<20170829202652.5476-1-stefan.bruens@rwth-aachen.de>\n\t<20170829202652.5476-3-stefan.bruens@rwth-aachen.de>","MIME-Version":"1.0","In-Reply-To":"<20170829202652.5476-3-stefan.bruens@rwth-aachen.de>","User-Agent":"NeoMutt/20170714 (1.8.3)","X-CRM114-Version":"20100106-BlameMichelson ( TRE 0.8.0 (BSD) ) MR-646709E3 ","X-CRM114-CacheID":"sfid-20170830_074903_936900_4C88D300 ","X-CRM114-Status":"GOOD ( 14.32 )","X-Spam-Score":"-1.9 (-)","X-Spam-Report":"SpamAssassin version 3.4.1 on bombadil.infradead.org summary:\n\tContent analysis details: (-1.9 points)\n\tpts rule name description\n\t---- ----------------------\n\t--------------------------------------------------\n\t-0.0 SPF_PASS SPF: sender matches SPF record\n\t-0.0 RP_MATCHES_RCVD Envelope sender domain matches handover relay\n\tdomain\n\t-1.9 BAYES_00 BODY: Bayes spam probability is 0 to 1%\n\t[score: 0.0000]","X-BeenThere":"linux-arm-kernel@lists.infradead.org","X-Mailman-Version":"2.1.21","Precedence":"list","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Cc":"Rob Herring , linux-sunxi@googlegroups.com,\n\tChen-Yu Tsai , linux-kernel@vger.kernel.org,\n\tlinux-arm-kernel@lists.infradead.org","Content-Type":"multipart/mixed;\n\tboundary=\"===============3817557085600485303==\"","Sender":"\"linux-arm-kernel\" ","Errors-To":"linux-arm-kernel-bounces+incoming-imx=patchwork.ozlabs.org@lists.infradead.org","List-Id":"linux-imx-kernel.lists.patchwork.ozlabs.org"}}]
