NAND_HW_CONTR(9) 					    Structures						   STRUCT NAND_HW_CONTR(9)

NAME
       struct_nand_hw_control - Control structure for hardware controller (e.g ECC generator) shared among independent devices

SYNOPSIS
       struct nand_hw_control {
	 spinlock_t lock;
	 struct nand_chip * active;
	 wait_queue_head_t wq;
       };

MEMBERS
       lock
	   protection lock

       active
	   the mtd device which holds the controller currently

       wq
