From: Johan Hovold <[email protected]> [ Upstream commit 4294625e029028854596865be401b9c5c1f906ef ]
The hci_bcm platform-device hack which was used to implement power management for ACPI devices is being replaced by a serial-device-bus implementation. Unfortunately, when the corresponding change to the ACPI code lands (a change that will stop enumerating and registering the serial-device-node child as a platform device) PM will break silently unless serdev TTY-port controller support has been enabled. Specifically, hciattach (btattach) would still succeed, but power management would no longer work. Although this is strictly a runtime dependency, let's make the driver depend on SERIAL_DEV_CTRL_TTYPORT, which is the particular serdev controller implementation used by the ACPI devices currently managed by this driver, to avoid breaking PM without anyone noticing. Note that the driver already has a (build-time) dependency on the serdev bus code.
