+From 2cf8e02af4645b90aa63f8cdbd0cb4403e2bee8f Mon Sep 17 00:00:00 2001
+From: Fraser <github@frasersdev.net>
+Date: Tue, 23 Feb 2016 10:04:37 +1100
+Subject: [PATCH 157/232] Aux SPI 1&2 implementation
+
+Adds aux spi 1 & 2 devices to compatible raspberry PIs.
+* Minor config of the driver build environment to ensure they get built
+for CONFIG_ARCH_BCM2708 & CONFIG_ARCH_BCM2709 devices.
+* Adds the aux spi driver into the defconfigs as a module.
+* Adds the auxiliary and spi1/2 devices into the device tree in a
+disabled state
+* Provides decide tree overlays which enables the devices and gives
+users a degree of control over how they are setup.
