      Bluetooth: btusb: Add out-of-band wakeup support · fd913ef7
      Rajat Jain authored
      Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that
      can be connected to a gpio on the CPU side, and can be used to wakeup
      the host out-of-band. This can be useful in situations where the
      in-band wakeup is not possible or not preferable (e.g. the in-band
      wakeup may require the USB host controller to remain active, and
      hence consuming more system power during system sleep).
      
      The oob gpio interrupt to be used for wakeup on the CPU side, is
      read from the device tree node, (using standard interrupt descriptors).
      A devcie tree binding document is also added for the driver. The
      compatible string is in compliance with
      Documentation/devicetree/bindings/usb/usb-device.txt

      Bluetooth: btqcomsmd: Fix module autoload · 747d3f1a
      Javier Martinez Canillas authored
      If the driver is built as a module, autoload won't work because the module
      alias information is not filled. So user-space can't match the registered
      device with the corresponding module.
      
      Export the module alias information using the MODULE_DEVICE_TABLE() macro.
      
      Before this patch:
      
      $ modinfo drivers/bluetooth/btqcomsmd.ko | grep alias
      $
      
      After this patch:
      
      $ modinfo drivers/bluetooth/btqcomsmd.ko | grep alias
      alias:          of:N*T*Cqcom,wcnss-btC*
      alias:          of:N*T*Cqcom,wcnss-bt
