From d57a4282d04810417c4ed2a49cbbeda8b3569b18 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sat, 7 Apr 2012 14:16:53 -0600 Subject: spi/devicetree: Move devicetree support code into spi directory The SPI device tree support code isn't shared by any other subsystem. It can be moved into the core drivers/spi directory and the exported symbol can be removed.
