[PATCH 0/4] iio: imu: bmi270: Match PNP ID found on gaming handheld firmwares

[Philip Mueller]

Within "Add i2c driver for Bosch BMI260 IMU" by Justin Weiss we had the following PNP IDs:

static const struct acpi_device_id bmi260_acpi_match[] = {
    {"BOSC0260", 0},
    {"BMI0260", 0},
    {"BOSC0160", 0},
    {"BMI0160", 0},
    {"10EC5280", 0},
    { },
};

Some of them weren't added when enabling BMI260 support within the bmi270 driver.
The following patches will fix that and enable several additional handhelds using the bmi270 driver properly.

Tested on close to final prototype of OrangePi Neo 2026 8840u model.

[PATCH 1/4] iio: imu: bmi270: Match PNP ID found on OrangePi Neo 2026

[Philip Mueller]

OrangePi Neo devices use BMI260 sensors in their hardware.
In older firmware they used "BMI0260" as their ID. In newer firmware
however they switched to "BOSC0260" as their ID for the sensors.
This change is also seen DSDT tables within newer device firmware.

Adding the PNP ID to bmi270 driver will load the driver properly on the device.

Hi Philip

The new one is not a PNP ID.  Those only have 3 letters.
They have switched over to using an ACPI ID - which is the other thing you
are allowed to put in _HID in ACPI.

Good to see they are using a valid format at least and hopefully Bosch
have indeed allocated that code to this device.  So rare case of a correct
update.

FWIW BMI was the PNP ID of the Benson medical instruments company.


So with a minor commit text update to reflect that I'll be happy to pick
this one up.

Thanks

Jonathan

[PATCH 2/4] iio: imu: bmi270: Match PNP ID found on OneXPlayer X1 Pro (AMD)

[Philip Mueller]

The OneXPlayer X1 Pro (AMD) uses 10EC5280 rather than BMI0260 or BOSC0260 as PNP ID.
Adding the ID will enable the BMI260 accelerometer on the device using the bmi270 driver.

Groan.  That's a realtech PCI ID not a PNP or ACPI ID.  Those can be used in
ACPI but far as I know realtech never made IMUs.  

More of an issue is this ID is already in the bmi160_i2c driver.
If they are using it for both parts we have a nasty problem
and it is probably a thing to fix as a platform quirk rather than in the
drivers.

There is a bunch of history of this ID 
https://lore.kernel.org/linux-iio/?q=10EC5280

IIRC Bosch provide their own mega driver supporting all parts from one module
and then do part detection.  Thus wrong tables often work :(

Yeah, this is in Realtek PCI scope which ACPI incorporates by
the specification, and yes, I have a long discussion about this
or similar IDs that are misused. If we go this way, this needs
a good shameful comment to point all this creepy choice made by
some unaware vendor(s).

Also, keep it ordered, I think this should go first in the table.

See also ca2f16c31568 ("Add 10EC5280 to bmi160_i2c ACPI IDs to allow binding on some devices")
for more details.

[PATCH 3/4] iio: imu: bmi270: add BOSC0160 PNP ID for gaming handhelds

[Philip Mueller]

Adding BOSC0160 as PNP ID will enable more gaming
handhelds using a BMI260 sensor with this PNP ID
to properly use the bmi270 driver.

Very short wrap. Go up to 75 characters.

As in early one, ACPI ID not PNP ID.  Ideally we'd also have confirmation
from bosch that they have assigned the IDs like this.  I ask in particular
because they have multiple parts with 160 numbers and they aren't
all supported by this driver. E.g. bmg160 which is a gyro only part.

+ Can we have at least one example part that is using this ID as
a comment inline.  Some of those earlier discussions of bosch IDs
identified ones that we were fairly sure were only ever used in
prototype devices.

Comment typos don't warrant fixes tags or stable inclusion.
That is even more so when the meaning of the text is clear even it
it is worth tidying up the typo going forwards.
