There are some boards out there which have a PL031 RTC, but its interrupt is not wired up. To support these, we need the PL031 to support the primecell without interrupts. When no interrupt is present, there's little point exposing the RTC's alarm capabilities, so we omit the alarm-related function calls - the RTC merely becomes a source of time-of-day. This patch series cleans up the pl031 driver a little, and adds support for this configuration. drivers/rtc/rtc-pl031.c | 48 +++++++++++++++++++++++++++--------------------- 1 file changed, 27 insertions(+), 21 deletions(-) v2: update patch 2 & 3 for review comment on v1. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up
