Subject: [PATCH v2 01/12] dt-binding: mediatek: Get rid of mediatek,larb for multimedia HW
Date: Mon, 10 Jun 2019 20:55:02 +0800	[thread overview]
Message-ID: <1560171313-28299-2-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1560171313-28299-1-git-send-email-yong.wu@mediatek.com>

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.
