rtc: omap: fix missing wakealarm attribute

2015-01-16T14:59:44Z

commit 7ecd9a3f062147400e605713724dd67dbb7e5053 upstream. The platform device must be registered as wakeup capable before registering the class device, or the wakealarm attribute will not be created. Also make sure to unregister the wakeup source on probe errors.

rtc: omap: fix clock-source configuration

2015-01-16T14:59:44Z

commit 44c63a570aaec3c5d5569d63b7c4a31ddd88cae0 upstream. This series fixes a few issues with the omap rtc-driver, cleans up a bit, adds device abstraction, and finally adds support for the PMIC control feature found in some revisions of this RTC IP block. Ultimately, this allows for powering off the Beaglebone and waking it up again on RTC alarms. This patch (of 20): Make sure not to reset the clock-source configuration when enabling the 32kHz clock mux. Until the clock source can be configured through device tree we must not overwrite settings made by the bootloader (e.g. clock-source selection).

drivers/rtc/rtc-omap.c: enable RTC_IRQWAKEEN bits when Alarm is set

2014-06-06T23:08:09Z

When RTC CLKTRCTRL bit is configured in HW_AUTO, module goes to sleep in IDLE state. The Alarm SWakeup event can be used to wakeup the RTC when it is in IDLE state. In order to do so, the alarm needs to be set and enabled before RTC enters the IDLE state. Also the wakeup generation for alarm/timer event needs to be set (bits [1:0] in RTC_IRQWAKEEN register). Currently RTC_IRQWAKEEN bits are set only in suspend/resume paths. With this ALARM interrupts are not generated when it enters IDLE state. So programming the RTC_IRQWAKEEN bits when ever ALARM is set.

drivers/rtc/rtc-omap.c: add support for enabling 32khz clock

2014-06-06T23:08:08Z

Newer versions of OMAP RTC IP such as those found in AM335x and DRA7x need an explicit enable of 32khz functional clock which ticks the RTC. AM335x support was working so far because of settings done in U-Boot. However, the DRA7x U-Boot does no such enable of 32khz clock and this patch is need to get the RTC to work on DRA7x at least. In general, it is better to not depend on settings done in U-Boot. Thanks to Lokesh Vutla for noticing this.

drivers/rtc/rtc-omap.c: use BIT() macro

2014-06-06T23:08:08Z

Use BIT() macro for RTC_HAS_ defines instead of hand-writing bit masks. Use BIT() macros for register bit field definitions. While at it, fix indentation done using spaces. No functional change in this patch. Signed-off-by: Sekhar Nori Cc: Alessandro Zummo Cc: Lokesh Vutla Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-omap.c: remove multiple device id checks

2014-06-06T23:08:08Z

Remove multiple superfluous device id checks. Since an id_table is present in the driver probe() should never encounter an empty device id entry. In case of OF style match, of_match_device() returns an matching entry. For paranoia sake, check for device id entry once and fail probe() if none is found. This is much better than checking for it multiple times. Signed-off-by: Sekhar Nori Cc: Alessandro Zummo Cc: Lokesh Vutla Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-omap.c: remove redundant of_match_ptr

drivers/rtc/rtc-omap.c: add rtc wakeup support to alarm events

2013-09-11T22:58:54Z

On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.

rtc: omap: restore back (hard-code) wakeup support

2013-07-03T23:08:00Z

rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms. However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry.
