From a20616863d32d91163043b6657a63c836bd9c5ba Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 26 Nov 2016 01:01:15 +0100 Subject: lantiq: use ath9k device tree bindings binding/owl-loader This moves the extraction of the eeprom/calibration data to a hotplug firmware script. Additionally it modifies all .dts to configure ath9k directly from within the .dts. The owl-loader approach enables support on devices with exotic eeprom data locations (such as unaligned positions on the flash or data inside an UBI volume).
