drivers/rtc/rtc-ab8500.c: add second resolution to rtc driver Android expects the RTC to have second resolution. On ab8540 cut2 RTC block has a new register which allows setting seconds for wakeup alarms. Existing registers (minutes hi, mid and low) have seen their offsets changed. Here is the new mapping: * AlarmSec (A) 0x22 * AlarmMinLow (M) from 0x8 to 0x23 * AlarmMinMid (M) from 0x9 to 0x24 * AlarmMinHigh (M) from 0xA to 0x25 Signed-off-by: Julien Delacou <julien.delacou@stericsson.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Cc: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

rtc: rtc-ab8500: remove unnecessary platform_set_drvdata() The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.

Drivers: rtc: remove __dev* attributes. 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.
