cfcb44872a iio: bmi270: suspend and resume triggering on relevant pm operations 
Prevent triggers from stop working after the device has entered sleep:
use iio_device_suspend_triggering and iio_device_resume_triggering helpers.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Scripted using

  git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
  do
    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {
        gsub(/__stringify\(ns\)/, "ns");

f35f3c832e iio: imu: bmi270: Add support for BMI260 
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 */
    }
    ...
}
