Subject: [RFC PATCH v3 1/7] iommu: provide early initialisation hook for IOMMU drivers
Date: Thu, 18 Sep 2014 15:31:54 +0100	[thread overview]

Hi Will,

After some fun times wondering why on Earth of_iommu_init was trying to 
instantiate a GIC, I think we may need one of these as part of this 
patch, too ;)

Robin.
