From: Bartosz Golaszewski <redacted> Enable cpufreq-dt support for da850-evm. The cvdd regulator is fixed at 1.2V on this board so disable the lower operating points and enable the 375MHz opp. Signed-off-by: Bartosz Golaszewski <redacted> --- arch/arm/boot/dts/da850-evm.dts | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+)
