Linux 7.2-rc2
Done to resolve conflicts with header reorg around mod_devicetable.h
and provide a base for other inflight series that touch the includes.
|
|
The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.

Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Currently BMI260 & BMI270 devices do not automatically load this
driver. To fix this, add missing MODULE_DEVICE_TABLE for the i2c,
acpi, and of device tables so the driver will load when the hardware
is detected.
Tested on my OneXPlayer F1 Pro.

The bmi270 can be connected to I2C or a SPI interface. If it is a SPI,
during probe, if devm_regmap_init() fails, it should print the "spi"
term rather "i2c".

Any-motion event can be enabled on a per-axis basis and triggers a
combined event when motion is detected on any axis.
No-motion event is triggered if the rate of change on all axes falls
below a specified threshold for a configurable duration. A fake channel
is used to report this event.
Threshold and duration can be configured from userspace.

GPD devices originally used BMI160 sensors with the "BMI0160" PNP ID.
When they switched to BMI260 sensors in newer hardware, they reused
the existing Windows driver which accepts both "BMI0160" and "BMI0260"
IDs. Consequently, they kept "BMI0160" in DSDT tables for new BMI260
devices, causing driver mismatches in Linux.
1. GPD updated BIOS v0.40+[1] for newer devices to report "BMI0260" for
BMI260 sensors to avoid loading the bmi160 driver on Linux. While this
isn't Bosch's VID;
2. Bosch's official Windows driver uses "BMI0260" as a compatible ID
3. We're seeing real devices shipping with "BMI0260" in DSDT
The DSDT excerpt of GPD G1619-04 with BIOS v0.40:

In the bmi270_configure_imu() function, the accelerometer and gyroscope
configuration registers are incorrectly written with the mask
BMI270_PWR_CONF_ADV_PWR_SAVE_MSK, which is unrelated to these registers.
As a result, the accelerometer's sampling frequency is set to 200 Hz
instead of the intended 100 Hz.
Remove the mask to ensure the correct bits are set in the configuration
registers.

driver. Setup and operation is nearly identical to the Bosch BMI270,
but has a different chip ID and requires different firmware.

Mini, Aya Neo AIR Pro, and OXP Mini Pro.
