From 3c1f6e358d4f1da4cf79083996544ce909f21b5f Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sat, 30 Aug 2014 09:32:58 +0000 Subject: ipq806x: Add support for IPQ806x chip family Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.
