Adds support for the Bosch BMI260 6-axis IMU to the Bosch BMI270
driver. Setup and operation is nearly identical to the Bosch BMI270,
but has a different chip ID and requires different firmware.
Firmware is requested and loaded from userspace.
Adds ACPI ID BMI0160, used by several devices including the GPD Win
Mini, Aya Neo AIR Pro, and OXP Mini Pro.
GPD Win Mini:
Device (BMI2)
{
Name (_ADR, Zero) // _ADR: Address
Name (_HID, "BMI0160") // _HID: Hardware ID
Name (_CID, "BMI0160") // _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 (0x0068, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.I2CB",
0x00, ResourceConsumer, , Exclusive,
)
GpioInt (Edge, ActiveLow, Exclusive, PullDefault, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x008B
}
})
Return (RBUF) /* \_SB_.I2CB.BMI2._CRS.RBUF */
}
...
}
