Subject: [PATCH v2 09/17] PM / devfreq: tegra30: Reset boosting on startup
Date: Wed, 26 Jun 2019 04:32:43 +0300 [thread overview]
Message-ID: <20190626013252.30470-10-digetx@gmail.com> (raw)
In-Reply-To: <20190626013252.30470-1-digetx@gmail.com>
Governor could be stopped while boosting is active. We have assumption
that everything is reset on governor's restart, including the boosting
value, which was missed.
