DSDT ROTM method seen in the wild with SMO8B30 _HID.
Making assumption it is similar to that used for bmc150 plus
information from Darrell that the rotation is out by 90 degrees at boot.

Method (ROTM, 0, NotSerialized)
{
    Name (RBUF, Package (0x03)
    {
        "0 -1 0",
        "1 0 0",
        "0 0 1"
    })
    Return (RBUF) /* \_SB_.PCI0.I2C5.DEV_.ROTM.RBUF */
}
