config CRYPTO_DEV_FSL_CAAM
	tristate "Freescale CAAM-Multicore driver backend"
	depends on FSL_SOC || ARCH_MXC
	help
	  Enables the driver module for Freescale's Cryptographic Accelerator
	  and Assurance Module (CAAM), also known as the SEC version 4 (SEC4).
	  This module creates job ring devices, 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.

	default y
	help
	  Enables the driver module for Job Rings which are part of
	  Freescale's Cryptographic Accelerator
	  and Assurance Module (CAAM). This module adds a job ring operation
	  interface.

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

	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

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

	  Note: the driver already provides adequate
	  interrupt coalescing in software.

	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

	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.

	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.

	  Selecting this will register the SEC4 hardware rng to
	  the hw_random API for suppying the kernel entropy pool.

	  will be called caamrng.

config CRYPTO_DEV_FSL_CAAM_RNG_TEST
	boolean "Test caam rng"
	depends on CRYPTO_DEV_FSL_CAAM_RNG_API
