From c9438affcb7ac0dda4c6c6961637fb272f7c32d4 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 4 Oct 2007 00:28:43 -0500 Subject: [POWERPC] Use for_each_ matching routinues for pci PHBs On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type.
