Hi, while I'm eagerly awaiting the outcome of the current situation regarding the "Move device tree graph parsing helpers to drivers/of" series, here is a draft implementation that parses the whole device tree into a separate graph structure, creating the backlinks internally. This way it doesn't matter to the code in which direction the phandle links in the device tree are pointing. The current code assumes a static device tree and doesn't handle runtime changes at all. I've also added two helpers to iterate over all ports of a device, and to obtain a specific port by its id (as contained in the 'reg' property). These patches are based directly on top of the previous series, which still can be found at: git://git.pengutronix.de/git/pza/linux.git topic/of-graph Philipp Zabel (3): of: Parse OF graph into graph structure of: Add OF graph helper to get a specific port by id of: Add OF graph helpers to iterate over ports drivers/of/base.c | 476 +++++++++++++++++++++++++++++++++++++++-------- include/linux/of_graph.h | 31 +++ 2 files changed, 430 insertions(+), 77 deletions(-) -- 1.9.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
