Hmm interesting I would expect there to be 2 ACPI devices for the
2 accelerometers and then things should just work fine.
Unless there is one DSDT entry / ACPI device with 2 i2c ACPI resources
to point to the 2 different accelerometers. That would not be the
first time I see that, we've some i2c helpers now to make dealing
with this easier.
Can you put an acpidump of the machine somewhere so that I can check
what is in the DSDT ?
A complete dump is available at https://github.com/larsks/yoga-11e-acpi/. It looks like there is a single ACPI device with two I2C devices; see https://github.com/larsks/yoga-11e-acpi/blob/master/dsdt.dsl#L10396.
Ah yes, ok I know how to fix this. It is not going to be 100% pretty from
a driver-code pov, but it should not be to bad and make both accelerometers
available. I will get back to you with a patch to test for this when
I've some time to whip up said patch.
Quick update on this, a colleague of mine, Jeremy Cline (added to the Cc)
was looking for some small projects to get up to speed wrt kernel development
so I've handed writing a patch for this over to him.
Regards,
Hans
