From ac2dee5984bc78c8ff1893142f7322320d2baf05 Mon Sep 17 00:00:00 2001 From: Rajkumar Kasirajan Date: Tue, 29 May 2012 15:07:40 -0700 Subject: [PATCH] drivers/rtc/rtc-pl031.c: remove RTC timer interrupt handling Remove RTT interrupt handling, since PIE mode interrupts are now better emulated in generic code via an hrtimer we have no need for this, and there is no codepath in the driver that enables these periodic interrupts anyway.
