From 15daf691e8e0119e6c21d3ddf6b4754e66e37365 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 15 Mar 2012 16:47:11 +0000 Subject: [PATCH] ARM: ux500: Enable PL022 SSP Controller in Device Tree This SSP Controller supports a number of serial communication methods and as such cannot be registered using of_register_spi_devices. Instead we register it simply as a primecell device.
