drivers/rtc/rtc-ab8500.c: ensure correct probing of the AB8500 RTC when Device Tree is enabled

2012-07-11T23:04:44+00:00

Without this patch, if Device Tree is enabled the AB8500 RTC wouldn't get probed at all, as there is no reference to it from platform code. This patch ensures the driver is probed during normal DT start-up.

drivers/rtc/rtc-ab8500.c: use IRQF_ONESHOT when requesting a threaded IRQ

2012-07-11T23:04:44+00:00

This driver's IRQ registration is failing because the kernel now forces IRQs to be ONESHOT if no IRQ handler is passed. Signed-off-by: Lee Jones Cc: Alessandro Zummo Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53+00:00

This patch converts the drivers in drivers/rtc/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

rtc/ab8500: add calibration attribute to AB8500 RTC

2012-01-11T00:30:52+00:00

The rtc_calibration attribute allows user-space to get and set the AB8500's RtcCalibration register. The AB8500 will then use the value in this register to compensate for RTC drift every 60 seconds.

drivers/rtc/rtc-ab8500.c: change msleep() to usleep_range()

2012-01-11T00:30:52+00:00

The resolution of msleep is related to HZ, so with HZ set to 100 any msleep of less than 10ms will become ~10ms. This is not what we want. Use the hrtimer-based usleep_range() and allow for some slack in the non-critical path so we have more control of what is happening here.

mfd: Unify abx500 headers in mfd/abx500

2012-01-08T23:37:39+00:00

This moves all the header files related to the abx500 family into a common include directory below mfd. From now on we place any subchip header in that directory. Headers previously in e.g. get prefixed and are now e.g. . The top-level abstract interface remains in . Signed-off-by: Linus Walleij Signed-off-by: Samuel Ortiz

mfd: Align ab8500 with the abx500 interface

2010-10-28T22:29:19+00:00

This patch makes the ab8500 mixed signal chip expose the same interface for register access as the ab3100, ab3550 and ab5500 chip. The ab8500_read() and ab8500_write() is removed and replaced with abx500_get_register_interruptible() and abx500_set_register_interruptible().
