* rtc: rv3029: hide unused i2c device tableArnd Bergmann2016-05-211-7/+7
| | | | | | | | | | | | | | The added support for SPI mode made it possible to configure the driver when I2C is disabled, leaving an unused device table: drivers/rtc/rtc-rv3029c2.c:794:29: error: 'rv3029_id' defined but not used [-Werror=unused-variable] This moves the table inside of the #ifdef section that has the only user, to avoid the harmless warning.

* rtc: rv3029: fix set_time functionMylène Josserand2016-05-211-1/+1
| | | | | | | | The bin2bcd function in set_time is uncorrect on weekdays as the bit mask should be done at the end of arithmetic operations. Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
* rtc: rv3029: fix alarm supportMylène Josserand2016-05-211-7/+16
| | | | | | | | | | | | | | | The RTC RV3029 handles different types of alarms : seconds, minutes, ... These alarms can be enabled or disabled individually using an AE_x bit which is the last bit (BIT(7)) on each alarm registers. To prepare the alarm IRQ support, the current code enables all the alarm types by setting each AE_x to 1. It also fixes others alarms issues : - month and weekday errors : it was performing -1 instead of +1. - wrong use of bit mask with bin2bcd Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

* 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.
