2016-06-26rtc: move mc146818 helper functions out-of-lineArnd Bergmann
The mc146818_get_time/mc146818_set_time functions are rather large inline functions in a global header file and are used in several drivers and in x86 specific code. Here we move them into a separate .c file that is compiled whenever any of the users require it. This also lets us remove the linux/acpi.h header inclusion from mc146818rtc.h, which in turn avoids some warnings about duplicate definition of the TRUE/FALSE macros.

2016-06-26mn10300: use RTC_DRV_CMOS instead of CONFIG_RTCArnd Bergmann
nn10300 has a dependency on mc146818_get_time/mc146818_set_time, which we want to move from the mc146818rtc.h header into the rtc subsystem, which in turn is not usable on mn10300. This changes mn10300 to use the modern rtc-cmos driver instead of the old RTC driver, and that in turn lets us completely remove the read_persistent_clock/update_persistent_clock callbacks.

2015-09-05rtc: pxa: convert to use shared sa1100 functionsRob Herring
Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a superset of functionality. Having 2 drivers sharing the same memory resource is not allowed by the driver model if resources are properly declared. This problem was avoided by not adding memory resources to the SA1100 RTC driver, but that prevents clean-up of the SA1100 driver. This commit converts the PXA RTC to use the exported SA1100 RTC functions. Now the sa1100-rtc and pxa-rtc devices are mutually exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

2015-09-05rtc: da9063: Add DA9062 RTC capability to DA9063 RTC driverS Twiss
Add DA9062 RTC support into the existing DA9063 RTC driver component by using generic access tables for common register and bit mask definitions. The following change will add generic register and bit mask support to the DA9063 RTC. The changes are slightly complicated by requiring support for three register sets: DA9063-AD, DA9063-BB and DA9062-AA. The following alterations have been made to the DA9063 RTC: - Addition of a da9063_compatible_rtc_regmap structure to hold all generic registers and bitmasks for this type of RTC component. - A re-write of struct da9063 to use pointers for regmap and compatible registers/masks definitions - Addition of a of_device_id table for DA9063 and DA9062 defaults - Refactoring functions to use struct da9063_compatible_rtc accesses to generic registers/masks instead of using defines from registers.h - Re-work of da9063_rtc_probe() to use of_match_node() and dev_get_regmap() to provide initialisation of generic registers and masks and access to regmap Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
