Please resubmit this patch once the\nabove dependencies are present in an rc release, which at this stage\nI expect to be v4.15-rc1.\n\n* ARM: dts: r8a7794: Add SMP support","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;
