====================
pull request: bluetooth-next 2015-12-11

Here's another set of Bluetooth & 802.15.4 patches for the 4.5 kernel:

 - 6LoWPAN debugfs support
 - New 802.15.4 driver for ADF7242 MAC IEEE802154
 - Initial code for 6LoWPAN Generic Header Compression (GHC) support
 - Refactor Bluetooth LE scan & advertising behind dedicated workqueue
 - Cleanups to Bluetooth H:5 HCI driver
 - Support for Toshiba Broadcom based Bluetooth controllers
 - Use continuous scanning when establishing Bluetooth LE connections

Please let me know if there are any issues pulling. Thanks.

* ADF7242 IEEE 802.15.4 *
Required properties:
- compatible: should be "adi,adf7242"
- spi-max-frequency: maximal bus speed (12.5 MHz)
- reg: the chipselect index
- interrupts: the interrupt generated by the device via pin IRQ1.
IRQ_TYPE_LEVEL_HIGH (4) or IRQ_TYPE_EDGE_FALLING (1)
Example:
adf7242@0 {
compatible = "adi,adf7242";
spi-max-frequency = <10000000>;
reg = <0>;
interrupts = <98 IRQ_TYPE_LEVEL_HIGH>;
interrupt-parent = <&gpio3>;
};
