Hi,

I understand that you are working without DT and your platform data
initialization is done in the board file
(arch/arm/mach-omap2/board-omap4panda.c
) ,right? 

It looks like you are not getting a response to the HCI command sent to the
wilink chip over UART.
Can you make sure that the BT_Enable pin is also muxed correctly and you see it
"high" when UART conversation starts?

Anyway for 3.9 the right thing to do would be to switch to using DT, however
device tree support is still missing for the ti-st and btwilink driver and the
device tree bindings for kim and btwilink are not yet in the .dtb files

I have just made the modifications to ti-st and btwilink and got bluetooth to
work for omap5-uevm, but this is no up-streamed yet.

Best Regards,
Eyal Reizer
