iio: imu: bmi270: Match PNP ID found on newer GPD firmware
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: Scope (_SB.I2CC) { Device (BMA2) { Name (_ADR, Zero) // _ADR: Address Name (_HID, "BMI0260") // _HID: Hardware ID Name (_CID, "BMI0260") // _CID: Compatible ID Name (_DDN, "Accelerometer") // _DDN: DOS Device Name Name (_UID, One) // _UID: Unique ID Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (RBUF, ResourceTemplate () { I2cSerialBusV2 (0x0069, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.I2CC", 0x00, ResourceConsumer, , Exclusive, ) }) Return (RBUF) /* \_SB_.I2CC.BMA2._CRS.RBUF */ } # omit some noise } } Link: http://download.softwincn.com/WIN%20Max%202024/Max2-7840-BIOS-V0.41.zip #1 Signed-off-by: Cryolitia PukNgae <cryolitia@uniontech.com> Reviewed-by: Andy Shevchenko <andy@kernel.org> Acked-by: Alex Lanzano <lanzano.alex@gmail.com> Link: https://patch.msgid.link/20250821-bmi270-gpd-acpi-v4-1-5279b471d749@uniontech.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
