Subject: [PATCH 3/4] OPP: Update the bandwidth on OPP frequency changes
Date: Wed, 13 Mar 2019 11:00:09 +0200 [thread overview]
Message-ID: <20190313090010.20534-4-georgi.djakov@linaro.org> (raw)
In-Reply-To: <20190313090010.20534-1-georgi.djakov@linaro.org>
If the OPP bandwidth values are populated, we want to switch also the
interconnect bandwidth in addition to frequency and voltage.
