Subject: [PATCH V4 03/20] dt-bindings: cpufreq: tegra124: remove vdd-cpu-supply from required properties
Date: Fri, 4 Jan 2019 11:06:45 +0800
Message-ID: <20190104030702.8684-4-josephl@nvidia.com> (raw)
In-Reply-To: <20190104030702.8684-1-josephl@nvidia.com>

The Tegra124 cpufreq driver works only with DFLL clock, which is a
hardware-based frequency/voltage controller. The driver doesn't need to
control the regulator itself. Hence remove that.
