From mboxrd@z Thu Jan 1 00:00:00 1970 From: anup.patel@broadcom.com (Anup Patel) Date: Wed, 27 Jan 2016 10:51:15 +0530 Subject: [RFC PATCH 2/6] iommu/arm-smmu: Invoke DT probe from arm_smmu_of_setup() In-Reply-To: <1453872079-27140-1-git-send-email-anup.patel@broadcom.com> References: <1453872079-27140-1-git-send-email-anup.patel@broadcom.com> Message-ID: <1453872079-27140-3-git-send-email-anup.patel@broadcom.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The SMMUv1/SMMUv2 driver is initialized very early using the IOMMU_OF_DECLARE() but the actual platform device is probed via normal DT probing. This patch uses of_platform_device_create() from arm_smmu_of_setup() to ensure that SMMU platform device is probed immediately.
