Subject: [PATCH 0/8] ethosu: Add Arm Ethos-U driver 

This series contains Arm's NPU Ethos-U driver for NXP i.MX93 platform.

Ethos-U Linux driver is to provide an example of how a rich operating
system like Linux can dispatch inferences to an Arm Cortex-M subsystem,
consisting of an Arm Cortex-M and an Arm Ethos-U NPU.
