Subject: [PATCH v2 1/3] dt-bindings: soc: qcom: Support GLINK intents
Date: Thu, 26 Oct 2017 15:28:54 -0700	[thread overview]
Message-ID: <1509056936-26578-2-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1509056936-26578-1-git-send-email-clew-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

Virtual GLINK channels may know what throughput to expect from a
remoteproc. An intent advertises to the remoteproc this channel is
ready to receive data. Allow a channel to define the size and amount of
intents to be prequeued.

Signed-off-by: Chris Lew <clew-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

Changes since v1:
- Change intents property to qcom,intents and update example
- Change second sentence in definition to better describe usage
