* drivers/rtc/rtc-rx8581.c: add SMBus-only adapters supportAndreas Werner2014-01-241-13/+68
| | | | | | | | | | | | | | | Add support for SMBus-only adapters (e.g. i2c-piix4). The driver has implemented only support for I2C adapters which implement the I2C_FUNC_SMBUS_I2C_BLOCK functionality before. With this patch it is possible to load and use the RTC driver with I2C and SMBUS adapters like the rtc-ds1307 does. Tested on AMD G Series Platform (i2c-piix4 adapter driver).

| | | | | | | | | | | After the switch to devm_* functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it.

* Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman2013-01-041-4/+4
| | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* drivers/rtc/rtc-rx8581.c: fix setdatetimeRudolf Marek2010-07-271-3/+17
| | | | | | | | | | | | | | Fix the logic while writing new date/time to the chip. The driver incorrectly wrote back register values to different registers and even with wrong mask. The patch adds clearing of the VLF register, which should be cleared if all date/time values are set.
