From 5df74352876c0835d2b41b53858c9ee779e0f12f Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Wed, 2 Jun 2010 00:39:54 +0200 Subject: MIPS: Loongson: Define rtc device on MC146818-equipped systems This patch declare the rtc device present on systems with clock compatible with the mc146818 and handled by rtc-cmos. Introduce a new Kconfig entry because there are some systems without rtc_cmos compatible clock.
