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

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

[Linus Walleij]

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.

ARM SoC folks: please apply this directly for v4.14, I have
no other ux500 DTS patches coming this merge window as far
as I know. It is just using standard bindings.
