[PATCH 1/4] ARM: dts: augment Ux500 to use DT cpufreq

Linus Walleij
2017-08-10T12:52:18Z

This adds the operating points to the Ux500 device tree and
deletes the old special-purpose cpufreq node, as we can now
use the generic DT cpufreq driver.

Viresh et al: I will merge this into ARM SoC separately from
the rest of the patches once we agree on this approach.
