From b9dbf9517784084ee9496f9f17f9754c1d021a9e Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 25 May 2012 16:03:44 +0900 Subject: clocksource: em_sti: Emma Mobile STI driver The STI hardware is based on a single 48-bit 32kHz counter that together with two individual compare registers can generate interrupts. There are no timer operating modes selectable which means that the timer can not clear on match. This driver is providing clocksource support for the 48-bit counter. Clockevents are also supported using the same timer in oneshot mode.
