* To instantiate an Anybus-S host, a controller should provide the following:
* - a reset function which resets the attached card;
* - a regmap which provides access to the attached card's dpram;
* - the irq of the attached card
* struct anybuss_ops - Controller resources to instantiate an Anybus-S host
* @reset: asserts/deasserts the anybus card's reset line.
* @regmap: provides access to the card's dual-port RAM area.
* @irq: number of the interrupt connected to the card's interrupt line.
* @host_idx: for multi-host controllers, the host index:
* 0 for the first host on the controller, 1 for the second, etc.
