/**
* 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).
