config CRYPTO_DEV_FSL_CAAM
	tristate "Freescale CAAM-Multicore driver backend"
	depends on FSL_SOC
	help
	  Enables the driver module for Freescale's Cryptographic Accelerator
	  and Assurance Module (CAAM), also known as the SEC version 4 (SEC4).
	  This module adds a job ring operation interface, and configures h/w
	  to operate as a DPAA component automatically, depending
	  on h/w feature availability.

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

config CRYPTO_DEV_FSL_CAAM_RINGSIZE
	int "Job Ring size"
	depends on CRYPTO_DEV_FSL_CAAM
	range 2 9
	default "9"
	help
	  Select size of Job Rings as a power of 2, within the
	  range 2-9 (ring size 4-512).
	  Examples:
		2 => 4
		3 => 8
		4 => 16
		5 => 32
		6 => 64
		7 => 128
		8 => 256
		9 => 512

config CRYPTO_DEV_FSL_CAAM_INTC
	bool "Job Ring interrupt coalescing"
	depends on CRYPTO_DEV_FSL_CAAM
	default y
	help
	  Enable the Job Ring's interrupt coalescing feature.

config CRYPTO_DEV_FSL_CAAM_INTC_COUNT_THLD
	int "Job Ring interrupt coalescing count threshold"
	depends on CRYPTO_DEV_FSL_CAAM_INTC
	range 1 255
	default 255
	help
	  Select number of descriptor completions to queue before
	  raising an interrupt, in the range 1-255. Note that a selection
	  of 1 functionally defeats the coalescing feature, and a selection
	  equal or greater than the job ring size will force timeouts.

config CRYPTO_DEV_FSL_CAAM_INTC_TIME_THLD
	int "Job Ring interrupt coalescing timer threshold"
	depends on CRYPTO_DEV_FSL_CAAM_INTC
	range 1 65535
	default 2048
	help
	  Select number of bus clocks/64 to timeout in the case that one or
	  more descriptor completions are queued without reaching the count
	  threshold. Range is 1-65535.

config CRYPTO_DEV_FSL_CAAM_CRYPTO_API
	tristate "Register algorithm implementations with the Crypto API"
	depends on CRYPTO_DEV_FSL_CAAM
	default y
	select CRYPTO_ALGAPI
	select CRYPTO_AUTHENC
	help
	  Selecting this will offload crypto for users of the
	  scatterlist crypto API (such as the linux native IPSec
	  stack) to the SEC4 via job ring.

	  To compile this as a module, choose M here: the module
	  will be called caamalg.
