Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Some Allwinner SoC have a crypto accelerator named
	  Security System. Select this if you want to use it.
	  The Security System handle AES/DES/3DES ciphers in CBC mode
	  and SHA1 and MD5 hash algorithms.

	  To compile this driver as a module, choose M here: the module
	  will be called sun4i-ss.

config CRYPTO_DEV_SUN4I_SS_DEBUG
	bool "Enable sun4i-ss stats"
	depends on CRYPTO_DEV_SUN4I_SS
	depends on DEBUG_FS
	help
	  Say y to enable sun4i-ss debug stats.
	  This will create /sys/kernel/debug/sun4i-ss/stats for displaying
	  the number of requests per algorithm.

	depends on PM
	help
	  Select y here to have support for the crypto Engine available on
	  Allwinner SoC H2+, H3, H5, H6, R40 and A64.
	  The Crypto Engine handle AES/3DES ciphers in ECB/CBC mode.

	  To compile this driver as a module, choose M here: the module
	  will be called sun8i-ce.

config CRYPTO_DEV_SUN8I_CE_DEBUG
	bool "Enable sun8i-ce stats"
	depends on CRYPTO_DEV_SUN8I_CE
	depends on DEBUG_FS
	help
	  Say y to enable sun8i-ce debug stats.
	  This will create /sys/kernel/debug/sun8i-ce/stats for displaying
	  the number of requests per flow and per algorithm.

config CRYPTO_DEV_SUN8I_CE_HASH
