Subject: RE: [PATCH] iommu: Drop the of_iommu_{set/get}_ops() interface

Hi Lorenzo,

>With the introduction of the new iommu_{register/get}_instance()
>interface in commit e4f10ffe4c9b ("iommu: Make of_iommu_set/get_ops() DT
>agnostic") (based on struct fwnode_handle as look-up token, so firmware
>agnostic) to register IOMMU instances with the core IOMMU layer there is
>no reason to keep the old OF based interface around any longer.
>
>Convert all the IOMMU drivers (and OF IOMMU core code) that rely on the
>of_iommu_{set/get}_ops() to the new kernel interface to register/retrieve
>IOMMU instances and remove the of_iommu_{set/get}_ops() remaining glue
>code in order to complete the interface rework.
