drivers/rtc/rtc-s5m.c: re-add support for devices without irq specified

2014-08-29T23:28:16Z

The rtc-s5m driver used to support devices without irq specified in the past. Re-add this support. The patch fixes boot for Insignal's Exynos4412 based Origen board.

drivers/rtc/rtc-tps65910.c: fix potential NULL-pointer dereference

2014-08-08T22:57:20Z

The interrupt handler gets the driver data associated with the RTC device and doesn't check it for validity. This can cause a NULL pointer being dereferenced when and interrupt fires before the driver data was properly set up. Fix this by setting the driver data earlier (before the interrupt is requested).

drivers/rtc/rtc-isl12022.c: device tree support

2014-08-08T22:57:20Z

Add support for configuring the ISL12022 real-time clock via the Device tree framework. This is based on what I've seen in the related ISL12057 driver, it has been tested and works on a Technologic Systems TS-7670 device which uses a ISL12020 RTC device, my device tree looks like this: apbx@80040000 { i2c0: i2c@80058000 { pinctrl-names = "default"; pinctrl-0 = <&i2c0_pins_a>; clock-frequency = <400000>; status = "okay"; isl12022@0x6f { compatible = "isl,isl12022"; reg = <0x6f>; }; }; ... etc }; Signed-off-by: Stuart Longland Cc: Roman Fietze Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: ia64: allow other architectures to use EFI RTC

2014-08-08T22:57:19Z

Currently, the rtc-efi driver is restricted to ia64 only. Newer architectures with EFI support may want to also use that driver. This patch moves the platform device setup from ia64 into drivers/rtc and allow any architecture with CONFIG_EFI=y to use the rtc-efi driver.
