From 110fa9797d3b9f7e71aa0ba55905d6ade9a68c00 Mon Sep 17 00:00:00 2001 From: Wenyou Yang Date: Fri, 24 Mar 2017 09:18:41 +0800 Subject: ARM: at91: dt: add dts files for sama5d3xek board Add the device tree files for sama5d3xek board. The dts files are copied from Linux-4.9, do the changes as below. - add reg property for the pinctrl node. - move the gpio nodes (pioA, pioB, pioC ...) as the pinctrl's slibling nodes. - add the "u-boot,dm-pre-reloc" property to determine which nodes which are needed by SPL and by the board_init_f stage. - fix the compile warning. - add spi0 node aliases.
