[PATCH] crypto: caam - add support for cmac(aes)

From: Iuliana Prodan Add cmac(aes) keyed hash offloading support. Similar to xcbc implementation, driver must make sure there are still some bytes buffered when ahash_final() is called. This way HW is able to decide whether padding is needed and which key to derive (L -> K1 / K2) for the last bl

[PATCH v4 3/4] tee: optee: add TEE bus device enumeration support

OP-TEE provides a pseudo TA to enumerate TAs which can act as devices/ services for TEE bus. So implement device enumeration using invoke function: PTA_CMD_GET_DEVICES provided by pseudo TA to fetch array of device UUIDs. Also register these enumerated devices with TEE bus as "optee-clntX" device.

[PATCH v4 4/4] hwrng: add OP-TEE based rng driver

On ARM SoC's with TrustZone enabled, peripherals like entropy sources might not be accessible to normal world (linux in this case) and rather accessible to secure world (OP-TEE in this case) only. So this driver aims to provides a generic interface to OP-TEE based random number generator service.

[PATCH v4 1/4] tee: add bus driver framework for TEE based devices

Introduce a generic TEE bus driver concept for TEE based kernel drivers which would like to communicate with TEE based devices/services. In this TEE bus concept, devices/services are identified via Universally Unique Identifier (UUID) and drivers register a table of device UUIDs which they can sup

[PATCH v4 2/4] tee: add supp_nowait flag in tee_context struct

This flag indicates that requests in this context should not wait for tee-supplicant daemon to be started if not present and just return with an error code. It is needed for requests which should be non-blocking in nature like ones arising from TEE based kernel drivers or any in kernel api that use

[PATCH v4 0/4] Introduce TEE bus driver framework

This series introduces a generic TEE bus driver concept for TEE based kernel drivers which would like to communicate with TEE based devices/ services. Patch #1 adds TEE bus concept where devices/services are identified via Universally Unique Identifier (UUID) and drivers register a table of device
