From eace566c3406cac3131d44198f05b7b55f79651f Mon Sep 17 00:00:00 2001 From: Chris Lew Date: Thu, 26 Oct 2017 15:28:54 -0700 Subject: dt-bindings: soc: qcom: Support GLINK intents 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.
