Subject: [PATCH v2 04/11] clk: tegra30: Mark certain clks as critical
Date: Fri, 27 May 2016 16:38:07 -0400 [thread overview]
Message-ID: <1464381494-27096-5-git-send-email-rklein@nvidia.com> (raw)
In-Reply-To: <1464381494-27096-1-git-send-email-rklein@nvidia.com>
Mark the required clks as critical so the core will enable them during
registration and therefore they will stay on.
