rtc: rv3029: fix alarm support
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>
