From: Christian Lamparter Date: Sun, 7 Jan 2018 20:27:48 +0000 (+0100) Subject: apm821xx: add linux 4.14 apm821xx patches X-Git-Tag: v18.06.0-rc1~1334 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=15faf389ad5159fa8223344029c98a0afca6e5ef apm821xx: add linux 4.14 apm821xx patches This patch updates the apm821xx target to use the 4.14 kernel. 4.14 finally ships with a driver for the WNDR4700's tc654 fan controller. The custom driver is deprecated in favor of the upstream driver and the thermal cooling definitions in the DTS are updated.
