[PATCH 0/2] mei: Add support for IVSC device

From: Wentong Wu
Date: Tue Nov 28 2023 - 07:35:06 EST


The Intel visual sensing controller (IVSC) device is designed to
control the camera sharing between host IPU for media usage and
IVSC for context sensing (face detection).

IVSC is exposed to host as a SPI device and the protocol used for
communicating with host is MEI. This driver implements the transport
protocol and MEI hardware interfaces for the IVSC device.

The firmware downloading for IVSC device is implemented as well.
