From 74b3597d0788da02228cca6d2712507932e0329d Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 23 Jan 2015 12:32:28 +0000 Subject: [PATCH] lantiq: correct value for fpi clock on ar9 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.
