[Qemu-ppc] [PATCH 05/31] dt: add helper for phandle enumeration |
Date: |
Wed, 6 Jun 2012 01:52:56 +0200 |
This patch adds a helper to search for a node's phandle by its path. This
is especially useful when the phandle is part of an array, not just a single
cell in which case qemu_devtree_setprop_phandle would be the easy choice.
