      platform/x86: Add and use a dual_accel_detect() helper · 153cca9c
      Hans de Goede authored
      Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers
      to allow the OS to determine the angle between the display and the base of
      the device.
      
      On Windows these are read by a special HingeAngleService process which
      calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is
      in tablet- or laptop-mode. The firmware may use this to disable the kbd and
      touchpad to avoid spurious input in tablet-mode as well as to report
      SW_TABLET_MODE info to the OS.
      
      Since Linux does not call these undocumented methods, the SW_TABLET_MODE
      info reported by various pdx86 drivers is incorrect on these devices.
      
      Before this commit the intel-hid and thinkpad_acpi code already had 2
      hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid
      reporting broken info.
      
      And now we also have a bug-report about the same problem in the intel-vbtn
      code. Since there are at least 3 different ACPI hardware-ids in play, add
      a new dual_accel_detect() helper which checks for all 3, rather then
      adding different hardware-ids to the drivers as bug-reports trickle in.
      Having shared code which checks all known hardware-ids is esp. important
      for the intel-hid and intel-vbtn drivers as these are generic drivers
      which are used on a lot of devices.
      
      The BOSC0200 hardware-id requires special handling, because often it is
      used for a single-accelerometer setup. Only in a few cases it refers to
      a dual-accel setup, in which case there will be 2 I2cSerialBus resources
      in the device's resource-list, so the helper checks for this.
