[PATCH 01/13] dt-binding: mediatek: Get rid of mediatek,larb for multimedia HW

From: Yong Wu
Date: Mon Dec 31 2018 - 23:52:31 EST


After adding device_link between the consumer with the smi-larbs,
if the consumer call its owner pm_runtime_get(_sync), the
pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. Thus, the consumer don't need the property.

And IOMMU also know which larb this consumer connects with from
iommu id in the "iommus=" property.

I guess it should go through Matthias's tree if the patch is ok,
thus I don't separate to different patches. If it's really needed,
please feel free to tell me.
