From 7aff0fe33033fc75b61446ba29d38b1b1354af9f Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Mon, 12 Dec 2011 09:25:58 -0700 Subject: of: Add of_property_match_string() to find index into a string list Add a helper function for finding the index of a string in a string list property. This helper is useful for bindings that use a separate *-name property for attaching names to tuples in another property such as 'reg' or 'gpios'.

There is no need to compile it for the rest of the PowerPC platforms or for any of the other architectures. This patch makes iseries and pseries select CONFIG_OF_DYNAMIC, and makes it default to off for everything else. It is still safe to turn on CONFIG_OF_DYNAMIC on all architectures, it just isn't necessary. v2: Also select OF_DYNAMIC for PPC_CHROMA and MPC885ADS as reported by Michael Meuling Signed-off-by: Grant Likely Acked-by: David S.
