| |
When RTC is used in 24H mode (and it is by this driver) the maximum hour value is 24 in BCD. This occupies bits [5:0] - which means correct mask for HOUR register is 0x3f not 0x1f. Fix the mask
Fixes: 32a4a4ebf768 ("rtc: bd70528: Initial support for ROHM bd70528 RTC") Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> ---
I just noticed this was never applied. I'd like to get this in as we currently have bd70528 RTC not working in few exiting releases. (Or it works as long as time is not set at the evening :/)
I think this once was in RTC tree but was dropped as Lee mentioned this belongs to MFD. Thus I dared to add the Alexandre's acked-by - please let me know if this is not Ok.
Lee, can you please pull this in so that we get the fix in-tree? I guess the fixes tag helps this to be included in some existing branches.
