Subject: cpufreq: dt: Add register helper
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d812734842f8ab3100e7cee8716b35be5a31a22a;p=thirdparty%2Flinux.git

cpufreq: dt: Add register helper

Cpufreq-dt currently exports no functions. This means that drivers that
are based on cpufreq-dt have no way of establishing a depmod dependency
on it. This helper allows that link.
