From bc0750e464d41e1234f56471b8f626b8d945b1a8 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 15 Nov 2018 14:32:02 +0100 Subject: clocksource/drivers/dbx500: Demote dbx500 PRCMU clocksource Demote the DBx500 PRCMU clocksource to quality 100 and mark it as NONSTOP so it will still be used for timekeeping across suspend/resume. The Nomadik MTU timer which has higher precision will be used when the system is up and running, thanks to the recent changes properly utilizing the suspend clocksources. This was discussed back in 2011 when the driver was written, but the infrastructure was not available upstream to use this timer properly. Now the infrastructure is there, so let's finalize the work.
