Got the spi working too. The it needs to be compatible with
ti,omap4-mcspi with four chip selects. Updated patch below.

Also added the pinctrl-single entry.

Subject: [PATCH] ARM: dts: Add basic dm816x device tree configuration

Similar to other omap variants, let's add dm816x support.

Note that this is based on generated data from the
TI81XX-LINUX-PSP-04.04.00.02 patches published at:

http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html

I've verified the basic functionality, but have not been
able to test all the devices on dm8168-evm.
