This adds a patch to target/linux/lantiq/patches-3.14 fixing a bug clock code on ar9. The current version returns the wrong value for the fpi clock frequency in some cases. See discussion for further details: https://lists.openwrt.org/pipermail/openwrt-devel/2015-January/030688.html I'm not sure about the patch naming and numbering convention. Do please let me know it this is not OK. Many thanks, Ben Mulvihill Signed-off-by: Ben Mulvihill <ben.mulvihill@gmail.com> SVN-Revision: 44083
