Cover letter [PATCH V5 0/7] iommu/msm: Add DT adaptation and generic bindings support

Hi Sricharan,

Thanks for the patchset,

Quoted 7 lines · Sricharan R

The msm_iommu.c driver currently works based on platform data.
A single master device can be connected to more than one iommu and multiple contexts in each of the iommu. This association between master and iommus was represented from platform data using parent/child devices. The master drivers were responsible for attaching all of the iommus/context to a domain. Now the platform data support is removed and DT support is added. The master/iommus are added through generic iommu bindings.
