From cba774ae8731699d39cbaf979aa4a0b351045924 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 30 Sep 2007 17:39:05 +0100 Subject: [PATCH] [ARM] Add rtc-cmos driver for ISA-based footbridge platforms ... but the rtc-cmos is rather broken; if PNP is enabled, it assumes that we have ACPI (!) which is quite bogus on these platforms - which may have ISAPNP but not ACPI. Something to be solved in the future.
