From 2ceb3ad705aa1abe6656b038bb9f4a6b1201cc35 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 19 Feb 2009 16:50:46 +0100 Subject: m68k: Hook up rtc-generic m68k has been a long time user of the generic RTC abstraction, so hook up rtc-generic: - Create the "rtc-generic" platform device if mach_hwclk is set, - Add checks for mach_hwclk, in anticipation of RTC chip drivers being moved to drivers/rtc/.
