Subject: [PATCH 0/4] Asynchronous notifications from secure world
Date: Wed, 9 Jun 2021 08:09:06 +0200 [thread overview]
Message-ID: <20210609060910.1500481-1-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 SPI interrupt is used to notify the driver that there are asynchronous
notifications pending.
Thanks,
Jens
