Subject: [PATCH v2 2/2] interconnect: qcom: Use icc_sync_state in sdm845 and osm-3l drivers
Date: Wed, 22 Jul 2020 14:01:39 +0300	[thread overview]
Message-ID: <20200722110139.24778-3-georgi.djakov@linaro.org> (raw)
In-Reply-To: <20200722110139.24778-1-georgi.djakov@linaro.org>

Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Let's
return the maximum amount of bandwidth as initial value. This bandwidth
level would be maintained until all consumers have probed.
