Subject: rtc: NXP pcf8563 vs Haoyu hym8563

Hi,

Erlier this year the hym8563 driver was added to the kernel. When I compared
the datasheets of the NXP pcf8563 (that I use) and the Haoyu hym8563 I 
cannot
find any significantdifferences between the two chips. Now is using 
different
drivers for the two similar (or identical?) chips:
a) A mistake
b) A feature
c) Me beeing stupid?

The difference between the drivers is handling of century and that the 
hym8563
driver support the clock output that both chips have.
