Sorry, it was not intentional. Wrong button.

I am not sure that I am following you. 

I can not use spi_master::cs_gpios, which is populated by 
of_spi_register_master(), because spi_register_master() 
populate SPI devices and they could issue setup method.

Requesting GPIO's in core framework is also not a easy
option because of arguments here[1].

Probably I am still missing something.
