Linux kernel configuration - set up ICC device tree node

In the linux add-in user's guide 1.2.0 at pag. 205 in the block 6.6.2 there is a description on how to reserver the pinmux signals in the linux kernel.

 

If I try to adapt the dts file with the sugested changes, I found there is some 'overlap' in the default file an the documentation.

In the default file there is already some pinctrl@0.

 

Should I add a new blobk in the scb, or should I mix both pinctrl@0 block toghether (as in the enclosed file ?).

 

I tried both, but in the <cat /sys/kernel/debug/pinctrl/pinctrl-adi2.0/pinmux-pins> I can't see the resevation.

 

Actually I try to combine the sharc talk-thru (bare-metal) with the linux kernel on the ARM processor.
