[PATCH 0/2] [SRU] [Trusty/master] built-in tsp65217 regulator support

While booting a Trusty kernel on a beaglebone board, logs are spammed with this:

...

that's because the cpufreq-cpu0 driver (that's built-in) requires the tsp65217
regulator driver that is compiled as a module (and not available during boot).

While it's only a warning and it goes away when the rootfs is mounted (and the
tps65217_regulator module is loaded), it's annoying and it spams the syslog.

Proposing for Trusty/master.
