dt-bindings: cpufreq: tegra124: remove vdd-cpu-supply from required properties (73688f7d) · Commits · 戴 / test

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. Cc: devicetree@vger.kernel.org Signed-off-by:
