Subject: [PATCH v8 06/10] OPP: Update the bandwidth on OPP frequency changes
Date: Tue, 12 May 2020 15:53:23 +0300	[thread overview]
Message-ID: <20200512125327.1868-7-georgi.djakov@linaro.org> (raw)
In-Reply-To: <20200512125327.1868-1-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.
