| |
Hi all,
I have a small issue with the i2c-i801 driver. It does not register the i2c adaptor due to an ACPI resource conflict:
[11074.459747] ACPI Warning: SystemIO range 0x000000000000f000-0x000000000000f01f conflicts with OpRegion 0x000000000000f000-0x000000000000f00f (\_SB_.PCI0.SBUS.SMBI) (20140214/utaddress-258) [11074.459761] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
With the code: err = acpi_check_resource_conflict(&dev->resource[SMBBAR]); if (err) { err = -ENODEV; goto exit; }
silently not activating the driver, however it still shows up in lspci -k. Commenting out the above code makes the driver provide the smbus interface as expected,
The question is: Is there any existing ACPI driver for this? I can't find any either under ACPI or i2c (i2c-scmi does not work for this).
Regards, Christian
