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. Regards, Tony 8< ------------------ From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Wed, 14 Jan 2015 17:45:22 -0800 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.
