[PATCH v4 0/3] iio: add support for Bosch BMX055 IMU

[PATCH v4 0/3] iio: add support for Bosch BMX055 IMU

[Jun Yan]

The BMX055[1] is a Bosch 9-axis IMU integrating a 3-axis accelerometer,
gyroscope and geomagnetic sensor.

It supports SPI/I²C interfaces, and existing compatible drivers can
be reused by simply adding the corresponding dt-bindings for fallback
coompatibles as follows:

- accelerometer: bmc150_accel
- gyroscope: bmg160
- magnetometer: bmc150_magn

Changes in v4:
- Please replace underscores with hyphens in the compatibles.
- Link to v3: https://lore.kernel.org/all/20260203143946.301233-1-jerrysteve1101@gmail.com/

Changes in v3:
- Drop the Linux-related comments in the bosch,bma25 dt-bindings.
- Link to v2: https://lore.kernel.org/all/20260202110304.236320-1-jerrysteve1101@gmail.com/

Changes in v2:
- Use fallback compatibles instead of introducing a new device ID in the driver.
- Link to v1: https://lore.kernel.org/all/20260129071105.389493-1-jerrysteve1101@gmail.com/

Applied and pushed out now.
