From 70f340df24518d36eeaefb6652d492f250115c19 Mon Sep 17 00:00:00 2001 From: Cyrille Pitchen Date: Wed, 27 Jan 2016 17:48:32 +0100 Subject: [PATCH] spi: atmel: fix gpio chip-select in case of non-DT platform The non-DT platform that uses this driver (actually the AVR32) was taking a bad branch for determining if the IP would use gpio for CS. Adding the presence of DT as a condition fixes this issue.
