Subject: [PATCH v4 00/34] Intel Vision Processing base enabling
From: Mark Gross <mgross@...ux.intel.com>
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 forth version of this patch set includes updates to the dt yaml files and
some missed updates from feedback given on the V2 patch set for keembay-vpu-ipc
and the Kconfig for intel_tsens
At the bottom of this coverletter is the delta between v2 and V3 for easy
review of the modifications. Feels like things are converging. :)
Thanks for looking at these and providing feedback.
