Intel Vision Processing Unit base enabling part 1

From: mark gross <[email protected]>

The Intel Vision Processing Unit (VPU) is an IP block that is showing up for the first time as part of the Keem Bay SOC. Keem Bay is a quad core A53 Arm SOC. It is designed to be used as a stand alone SOC as well as in an PCIe Vision Processing accelerator add in card.

This part 1 of the patches make up the base or core of the stack needed to enable both use cases for the VPU.

Part 2 includes 11 more patches that depend on part 1. Those should be ready in a couple of weeks or less.

I am trying something a bit new with this sequence where I've been working with the driver developers as a "pre-maintainer" reviewing and enforcing the kernel expectations as I understand them. Its taken a couple of months to get this code to the point I feel its ready for public posting. My goal is to make sure it meets expectations for quality and compliance with kernel expectations and there will be mostly technical / design issues to talk about.

Thanks for looking at these and providing feedback.

p.s. I have had a problem my MTA configuration between mutt and git send-email where I was using msmpt to send from mutt (because 15+ years ago its the first way I got to work and never changed) while my worstation MTA that git send-email uses was un-configured resulting in my return-path naming my workstion withing the firewall. I suck at email administration.

I appologies for the multiple copies.
