From 324873e7c268338dd2ba84c1fab4340ab68a312c Mon Sep 17 00:00:00 2001 From: "Wenyou.Yang@microchip.com" Date: Fri, 21 Jul 2017 13:28:40 +0800 Subject: board: at91sam9261ek: Update to support DT and DM Add the dts files to support deivce tree, update the configuration files to support the device tree and driver model. The peripheral clock and pins configuration are handled by the clock and the pinctrl drivers respectively. Enable the early debug UART to debug problems when an ICE or other debug mechanism is not available.
