Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next
Johan Hedberg says: ==================== pull request: bluetooth-next 2016-05-07 Here are a few more Bluetooth patches for the 4.7 kernel: - NULL pointer fix in hci_intel driver - New Intel Bluetooth controller id in btusb driver - Added device tree binding documentation for Marvel's bt-sd8xxx - Platform specific wakeup interrupt support for btmrvl driver Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

+Marvell 8897/8997 (sd8897/sd8997) bluetooth SDIO devices
+------
+
+Required properties:
+
+ - compatible : should be one of the following:
+ * "marvell,sd8897-bt"
+ * "marvell,sd8997-bt"
+
+Optional properties:
+
+ - marvell,cal-data: Calibration data downloaded to the device during
+ initialization. This is an array of 28 values(u8).
+
+ - marvell,wakeup-pin: It represents wakeup pin number of the bluetooth chip.
+ firmware will use the pin to wakeup host system.
+ - marvell,wakeup-gap-ms: wakeup gap represents wakeup latency of the host
+ platform. The value will be configured to firmware. This
+ is needed to work chip's sleep feature as expected.
+ - interrupt-parent: phandle of the parent interrupt controller
+ - interrupts : interrupt pin number to the cpu. Driver will request an irq based
+ on this interrupt number. During system suspend, the irq will be
+ enabled so that the bluetooth chip can wakeup host platform under
+ certain condition. During system resume, the irq will be disabled
+ to make sure unnecessary interrupt is not received.
+
+Example:
+
+IRQ pin 119 is used as system wakeup source interrupt.
+wakeup pin 13 and gap 100ms are configured so that firmware can wakeup host
+using this device side pin and wakeup latency.
+calibration data is also available in below example.
