From 1c043f16a01c144305e952025e883b55706f2450 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Thu, 10 Nov 2011 12:06:22 +0000 Subject: MIPS: Alchemy: Add RTC device to all devboards All Devboards can use the 32kHz counter as a RTC device. Also delete the custom CMOS RTC header, which can be used for the DS1693 on the PB1500. But since it doesn't have a buffer battery it is as useful as the on-chip RTC which I prefer.
