rtc: hym8563: fix invalid year calculation

2016-07-11T03:07:13Z

[ Upstream commit d5861262210067fc01b2fb4f7af2fd85a3453f15 ] Year field must be in BCD format, according to hym8563 datasheet. Due to the bug year 2016 became 2010.

drivers/rtc/rtc-hym8563.c: fix swapped enable/disable of clockout control bit

2015-04-17T13:04:02Z

The hym8563 datasheet describes the clock output control-bit as "when set to logic 0, the square wave output is enable, when set to logic 1, the CLKOUT output is inhibited". But in reality the setting is exactly opposite. Before now, the clock output was not really used, but on the rk3288 soc this generated clock is used to supply the temperature sensor block and the swapped bit value prevented it from working. With the corrected value, the tsadc now reports correct values.

drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled

2015-04-17T13:04:01Z

When the clock is disabled, do not return a rate of 0 but instead return the rate the clock will be running at after it gets enabled. This prevents problems when the core clock code is trying to determine a suitable rate, while the clock is still off.

drivers/rtc/rtc-hym8563.c: add optional clock-output-names property

2014-06-06T23:08:08Z

This enables the setting of a custom clock name for the clock provided by the hym8563 rtc. Signed-off-by: Heiko Stuebner Reviewed-by: Mike Turquette Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-hym8563: make of_device_id array const

2014-06-06T23:08:07Z

Make of_device_id array const, because all OF functions handle it as const. Signed-off-by: Jingoo Han Acked-by: Heiko Stbner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-hym8563.c: set uie_unsupported

2014-05-11T08:55:48Z

The alarm of the hym8563 only supports a minute accuracy, while the uie wants an alarm one second in the future. Therefore things like the select() syscall will fail with a timeout, because the next alarm will happen in a worst case of 60 seconds.
