From 699bc6614f4d5a68b8840d4d859e9ca205530a77 Mon Sep 17 00:00:00 2001 From: Markus Brunner Date: Thu, 26 Jul 2007 17:31:28 +0900 Subject: rtc: rtc-sh: Correct sh_rtc_set_time() for some SH-3 parts. Some SH-3 parts (SH7720 and SH7705 at least) need to have the start bit explicitly cleared, as the reset is not enough. This is safe across all parts, so simply clear the start bit in the sh_rtc_set_time() path.
