Subject: [PATCH v6 6/9] soc: mediatek: mmsys: instantiate mdp virtual device from mmsys
Date: Mon, 2 Aug 2021 22:12:12 +1000 [thread overview]
Message-ID: <20210802220943.v6.6.Ie4214d2cc73ab276dd7c41d4f63c98e011fb42d4@changeid> (raw)
In-Reply-To: <20210802121215.703023-1-eizan@chromium.org>
A virtual device that is probed by the mtk_mdp_core driver is
instantiated by the mtk_mmsys driver.
This better reflects the logical organization of the hardware and
driver: there are a number of hardware blocks that are used by the MDP
that have no strict hierarchy, and the software driver is responsible
for driving them properly.
