To solve this, a number of IOMMU drivers use initcalls to initialise the driver before anything has a chance to be probed. Whilst this solves the immediate problem, it leaves the job of probing the IOMMU completely separate from the iommu_ops to configure the IOMMU, which are called on a per-bus basis and require the driver to figure out exactly which instance of the IOMMU is being requested. In particular, the add_device callback simply passes a struct device to the driver, which then has to parse firmware tables or probe buses to identify the relevant IOMMU instance. This patch takes the first step in addressing this problem by adding an early initialisation pass for IOMMU drivers, giving them the ability to store some per-instance data in their iommu_ops structure and store that in their of_node. This can later be used when parsing OF masters to identify the IOMMU instance in question.
