Subject: Re: [PATCH v2 0/2] misc: mei: Add support for IVSC device

Wentong,

On mainline v6.6, I cherry-picked IVSC/LCJA related patches and these v2 
patches, added Intel IPU6 driver on Github, then made some changes on 
IPU6 HAL to auto link IVSC device. I tested the build on a Dell Latitude 
7440 which is using HI556 camera sensor and it previews normally.

If it's properly, you can add my "Tested-by:" tag.
