rtc: hym8563: set uie_unsupported
From: Heiko Stuebner <heiko@...> Date: Tue, 6 May 2014 18:45:45 +0200
Commit-Message
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.
