Subject: [PATCH v2 0/7] Asynchronous notifications from secure world
Date: Wed, 16 Jun 2021 12:36:42 +0200 [thread overview]
Message-ID: <20210616103649.2662395-1-jens.wiklander@linaro.org> (raw)
Hi all,
This adds support for asynchronous notifications from OP-TEE in secure
world to the OP-TEE driver. This allows a design with a top half and bottom
half type of driver where the top half runs in secure interrupt context and
a notifications tells normal world to schedule a yielding call to do the
bottom half processing.
An interrupt is used to notify the driver that there are asynchronous
notifications pending.
v2:
* Added documentation
* Converted optee bindings to json-schema and added interrupt property
* Configure notification interrupt from DT instead of getting it
from secure world, suggested by Ard Biesheuvel <ardb@kernel.org>.
Thanks,
Jens
