Return-Path: From: Frederic Danis To: linux-bluetooth@vger.kernel.org Subject: [PATCH v4 0/5] Bluetooth: hci_bcm: Add wake-up and PM runtime support Date: Tue, 15 Sep 2015 10:31:03 +0200 Message-Id: <1442305868-6203-1-git-send-email-frederic.danis@linux.intel.com> Content-Type: text/plain; charset="utf-8" Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Add wake-up capabilities by retrieveing interruption used by BCM device in ACPI table. Add PM runtime support. 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.
