From fe6da4837308aa33d537ac3e7f36c2d66e3d9a36 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 12 May 2009 15:17:35 +0200 Subject: MPC8260: fixup device tree by property instead of path cpu/mpc8260/cpu.c used to use do_fixup_by_path_u32() to update the clock frequencies in the device tree, using a CPU path "/cpus/OF_CPU", with OF_CPU beind defined in the board config file. However, this does not work when one board config file (here: MPC8260ADS.h) is intended to be used for several diffrent CPUs and therefor contains a generic definition like "cpu@0", as the device trees that will then be loaded will contain specific names like "PowerPC,8272@0". We switch to using do_fixup_by_prop_u32() instead, so we can search for device_type="cpu", as it is done in other architectures, too.
