/**

 * 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).
