From e7f68403f49e901732df3c02731b6e714cfbe417 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 23 Jan 2017 11:41:51 +0100 Subject: ARM: sun8i: a23/a33: Enable the real LOSC and use it So far, the LOSC was generated through the RTC internal oscillator, which was a pretty poor and inaccurate choice. Now that the RTC properly exposes its internal mux between its oscillator and the external oscillator, we can use it were relevant.
