Merge tag 'tee-drv-async-supplicant-for-v4.16' of https://git.linaro.org/people/jens.wiklander/linux-tee into next/drivers
Pull "Enable async communication with tee supplicant" from Jens Wiklander:
This pull request enables asynchronous communication with TEE supplicant
by introducing meta parameters in the user space API. The meta
parameters can be used to tag requests with an id that can be matched
against an asynchronous response as is done here in the OP-TEE driver.
Asynchronous supplicant communication is needed by OP-TEE to implement
GlobalPlatforms TEE Sockets API Specification v1.0.1. The specification
is available at https://www.globalplatform.org/specificationsdevice.asp.
This change is backwards compatible allowing older supplicants to work
with newer kernels and vice versa.
* tag 'tee-drv-async-supplicant-for-v4.16' of https://git.linaro.org/people/jens.wiklander/linux-tee:
optee: support asynchronous supplicant requests
tee: add TEE_IOCTL_PARAM_ATTR_META
tee: add tee_param_is_memref() for driver use
