Subject: [PATCH 4/6] dt-bindings: media: venus: describe sdm845 with optional pmdomains
Date: Mon, 9 Dec 2019 10:38:22 +0200 [thread overview]
Message-ID: <20191209083824.806-5-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20191209083824.806-1-stanimir.varbanov@linaro.org>
Describe an optional DT binding for sdm845 with power-domain-names
and clocks in Venus DT node. After that the binding for sdm845 will
have two options, the first will be to describe vcodec clocks and
pmdomains in (encoder and decoder) subnodes and the second will be
to describe vcodec clocks and pmdomains in the Venus DT node
(the parent). Both option will be handled in driver, and the second
one will give an opportunity to the driver to dynamically assign
vcodec pipelines for every given instance depending on its load.
