[PATCH v2 00/10] Bluetooth on 2015+ MacBook (Pro)

[Lukas Wunner <lukas@wunner.de>]

Enable UART-attached Bluetooth on 2015+ MacBook (Pro), v2.

Changes since v1:

- New patch [1/10] to make Bluetooth drivers depend on rather than select
  GPIOLIB. (Andy, Linus)

- New patch [2/10] to enforce presence of shutdown and device wake GPIO.
  (Andy, Linus, Loic)

- Split off hunks:
  to enable runtime PM despite absence of IRQ into patch [3/10],
  to validate the IRQ before using it into patch [4/10],
  to add a helper to toggle device wake GPIO into patch [5/10]. (Marcel)

- In patch [5/10], I had previously forgotten to toggle the device wake
  GPIO in bcm_gpio_set_power() on Macs, this is now fixed.

- New patch [6/10] to silence an irritating IRQ printk.

- New patch [7/10] to clean up an unnecessary #ifdef.

- New patch [8/10] to add kerneldoc for struct bcm_device.

- New patch [9/10] to add proper error handling to the driver.

- In patch [10/10]:
  add DSDT excerpt to the commit message,
  drop ternary operators for readability,
  return -EIO instead of -EFAULT if ACPI method calls fail,
  return -EOPNOTSUPP in inline stubs,
  use network subsystem comment style. (Marcel, Hans, Andy)
  Also, to accommodate to mandatory presence of the two GPIOs as per
  patch [2/10], rename bcm_apple_probe() to bcm_apple_get_resources()
  and call it from bcm_get_resources() instead of bcm_acpi_probe().
