Add wake-up capabilities by retrieveing interruption used by BCM device in ACPI
table.
Add PM runtime support.
v4->v5:
- Add bt_warn to to unify Bluetooth traces in BT_WARN
- Change bcm_suspend_device/bcm_resume_device prototype to be usable directly
in SET_RUNTIME_PM_OPS. This allows to remove bcm_runtime_suspend/bcm_runtime_resume
which just call bcm_suspend_device/bcm_resume_device.
- Update commit message and add comment in hci_uart_tty_receive to explain
why spin_lock is not requested
v3->v4:
- Add new BT_WARN and bt_dev_warn logging macros
- Use bt_dev_warn for T100 irq polarity fix
- Rename __bcm_suspend to bcm_suspend_device,
and __bcm_resume to bcm_resume_device
- Remove useless rx_lock spinlock. It is only used in hci_uart_tty_receive() which
is the receive_buf ldisc callback. This is already protected by flush_to_ldisc()
in drivers/tty/tty_buffer.c.
This allows to use mutex in bcm_recv() and call pm_runtime_* directly
- Remove pm_work Work queue which is now useless
- Delay auto-suspend only when reception of a packet is completed
v2->v3:
- Use DMI_EXACT_MATCH instead of DMI_MATCH
- Fix IRQ polarity for T100TA in driver_data of dmi_system_id struct
- Use dmi_first_match() instead of dmi_check_system()
v1->v2:
- Split 1st patch between general wake-up capability and T100TA IRQ fix
- Replace multiple "if ... else if" by switch in bcm_resource()
- Move code to limit number of #ifdef
- Use DMI info to restrict IRQ to T100TA
- Split 2nd patch to prepare PM runtime support in separated patch
- Tested with and without CONFIG_PM_SLEEP and CONFIG_PM.
