Subject: [PATCH 00/15 v2] iommu: Move iommu_fwspec out of 'struct device'

Hi,

here is a patch-set to rename iommu_param to dev_iommu and
establish it as a struct for generic per-device iommu-data.
Also move the iommu_fwspec pointer from struct device into
dev_iommu to have less iommu-related pointers in struct
device.

The bigger part of this patch-set moves the iommu_priv
pointer from struct iommu_fwspec to dev_iommu, making is
usable for iommu-drivers which do not use fwspecs.

The changes for that were mostly straightforward, except for
the arm-smmu (_not_ arm-smmu-v3) and the qcom iommu driver.
Unfortunatly I don't have the hardware for those, so any
testing of these drivers is greatly appreciated.

Please review.

Regards,

	Joerg
