+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.
