[RESEND PATCH v5 4/5] ARM: dts: da850-evm: enable cpufreq

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

Enable cpufreq-dt support for da850-evm. The cvdd is supplied by the
tps65070 pmic with configurable output voltage. By default da850-evm
boards support frequencies up to 375MHz so enable this operating
point.
