	  The IERB contains registers that are used for pre-boot initialization,
	  debug, and non-customer configuration. The PRB controls global reset
	  and global error handling for NETC. The NETCMIX block is mainly used
	  to set MII protocol and PCS protocol of the links, it also contains
	  settings for some other functions.

	  If compiled as module (M), the module name is nxp-netc-blk-ctrl.
