Subject[PATCH 0/3] optee: async notif with PPI + interrupt provider
Date
Dear all,

This small series aggregates 2 change proposals related to OP-TEE async notif.
I've made a single series since the 2 patches hit the same portions of optee
driver source file and I think this will help the review. If you prefer having
independent post and deal with the conflicts afterward, please tell me.

Patch "optee: add per cpu asynchronous notification" aims at allowing optee
to use a per-cpu interrupt (PPI on Arm CPUs) for async notif instead of a
shared peripheral interrupt.

The 2 next patches implement a new feature in OP-TEE, based on optee async
notif. The allow optee driver to behave as an interrupt controller, for
when a secure OP-TEE event is to be delivered to the Linux kernel as a
interrupt event.

Regards,
Etienne
