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.
