/**
 * struct s5p_aes_dev - Crypto device state container
 * @dev:	Associated device
 * @clk:	Clock for accessing hardware
 * @ioaddr:	Mapped IO memory region
 * @aes_ioaddr:	Per-varian offset for AES block IO memory
 * @irq_fc:	Feed control interrupt line
 * @req:	Crypto request currently handled by the device
 * @ctx:	Configuration for currently handled crypto request
 * @sg_src:	Scatter list with source data for currently handled block
 *		in device.  This is DMA-mapped into device.
 * @sg_dst:	Scatter list with destination data for currently handled block
 *		in device. This is DMA-mapped into device.
 * @sg_src_cpy:	In case of unaligned access, copied scatter list
 *		with source data.
 * @sg_dst_cpy:	In case of unaligned access, copied scatter list
 *		with destination data.
 * @tasklet:	New request scheduling jib
 * @queue:	Crypto queue
 * @busy:	Indicates whether the device is currently handling some request
 *		thus it uses some of the fields from this state, like:
 *		req, ctx, sg_src/dst (and copies).  This essentially
 *		protects against concurrent access to these fields.
 * @lock:	Lock for protecting both access to device hardware registers
 *		and fields related to current request (including the busy field).
