Dear all, I am trying to get the cameras in a Lenovo IdeaPad Miix 320 (Atom x5-Z8350 BayTrail) to work. The front camera is an ov2680. With kernel 4.14.4 and 4.15rc3 I see the following dmesg output: [ 21.469907] ov2680: module is from the staging directory, the quality is unknown, you have been warned. [ 21.492774] ov2680 i2c-OVTI2680:00: gmin: initializing atomisp module subdev data.PMIC ID 1 [ 21.492891] acpi OVTI2680:00: Failed to find gmin variable OVTI2680:00_CamClk [ 21.492974] acpi OVTI2680:00: Failed to find gmin variable OVTI2680:00_ClkSrc [ 21.493090] acpi OVTI2680:00: Failed to find gmin variable OVTI2680:00_CsiPort [ 21.493209] acpi OVTI2680:00: Failed to find gmin variable OVTI2680:00_CsiLanes [ 21.493511] ov2680 i2c-OVTI2680:00: i2c-OVTI2680:00 supply V1P8SX not found, using dummy regulator [ 21.493550] ov2680 i2c-OVTI2680:00: i2c-OVTI2680:00 supply V2P8SX not found, using dummy regulator [ 21.493569] ov2680 i2c-OVTI2680:00: i2c-OVTI2680:00 supply V1P2A not found, using dummy regulator [ 21.493585] ov2680 i2c-OVTI2680:00: i2c-OVTI2680:00 supply VPROG4B not found, using dummy regulator [ 21.568134] ov2680 i2c-OVTI2680:00: camera pdata: port: 0 lanes: 1 order: 00000002 [ 21.568257] ov2680 i2c-OVTI2680:00: read from offset 0x300a error -121 [ 21.568265] ov2680 i2c-OVTI2680:00: sensor_id_high = 0xffff [ 21.568269] ov2680 i2c-OVTI2680:00: ov2680_detect err s_config.
