From 60ed7951d0c9bf8de8588384134f16474367b410 Mon Sep 17 00:00:00 2001 From: Alex Date: Mon, 17 Mar 2008 14:55:06 +0100 Subject: avr32: Allow board to define oscillator rates On our custom board we have other oscillator rates than on atngw100 and atstk100x. Currently these rates are hardcoded in arch/avr32/mach-at32ap/at32ap700x.c. This patch moves them into board specific code.
