I see that the ivsc driver has not been in master branch. Before that, could you try several hack to check whether camera can work on master? https://github.com/bingbucao/linux/commits/ipu_dev 7ebff51284d9 media: ov01a10: hack ivsc to make camera can work 01cc9f3d1b61 i2c: ljca: Call acpi_dev_clear_dependencies() 92e5d122e105 vsc: Defer firmware loading to avoid long probing time 5f5d5f0df06b driver: ivsc: add intel ivsc driver 0f4819dec533 Revert "gpio: Add support for Intel LJCA USB GPIO driver" > >> >> Regards >> Claus Stovgaaard >> > -- Best regards, Bingbu Cao
