2024-04-11	mei: vsc: Unregister interrupt handler for system suspend	Sakari Ailus	1	-0/+3
	Unregister the MEI VSC interrupt handler before system suspend and re-register it at system resume time. This mirrors implementation of other MEI devices. This patch fixes the bug that causes continuous stream of MEI VSC errors after system resume.

2023-12-07	mei: Add transport driver for IVSC device	Wentong Wu	1	-0/+50
	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 an SPI device and the message protocol over the SPI BUS for communicating with the IVSC device is implemented. This is the backend of mei framework for IVSC device, which usually handles the hardware data transfer. The mei_csi and mei_ace are the clients of IVSC mei framework. The firmware downloading for the IVSC device is implemented as well.
