-Subject: [PATCH] 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.
