From 04f7e3e5134b9517bd9a78a84a9ee0f982d3ebdd Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Mon, 29 Sep 2014 01:50:05 +0200 Subject: clocksource: vf_pit_timer: Support shutdown mode In order to avoid waking up the system in a low power mode, the clocksource should not generate interrupts anymore. Disable the PIT timer interrupt when changing into the CLOCK_EVT_MODE_SHUTDOWN mode.
