How can I access directly to the configuration registers for the SPI module?

For example, register SPIx_MCR, for configure Fast Continuous Selection Format.


I have tried with IOCTL functions, but SPIDev library only have a few configuration parameters (mode, lsb_first, bits_per_word, max_speed,..,), and it dont allow advanced configurations.


- Kernel 4.14.78

- Yocto Warrior.

- C code.


Thank you.
