Not knowing what to install for ntp, I tried:
yum install ntp*
And got the following errors:
Error: Package: ntp-perl-4.2.6p5-19.el7.centos.noarch (c7buildroot)
Requires: ntp = 4.2.6p5-19.el7.centos
Installing: ntp-4.2.6p5-19.el7.armv7hl (c7pass1)
ntp = 4.2.6p5-19.el7

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Just doing: yum install ntp
got at least ntp installed. But afterwards: yum install ntp*
still gets these messages.
