====================
pull request: bluetooth-next 2015-10-08

Here's another set of Bluetooth & 802.15.4 patches for the 4.4 kernel.

802.15.4:
 - Many improvements & fixes to the mrf24j40 driver
 - Fixes and cleanups to nl802154, mac802154 & ieee802154 code

Bluetooth:
 - New chipset support in btmrvl driver
 - Fixes & cleanups to btbcm, btmrvl, bpa10x & btintel drivers
 - Support for vendor specific diagnostic data through common API
 - Cleanups to the 6lowpan code
 - New events & message types for monitor channel

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

* MRF24J40 IEEE 802.15.4 *
Required properties:
- compatible: should be "microchip,mrf24j40", "microchip,mrf24j40ma",
or "microchip,mrf24j40mc" depends on your transceiver
board
- spi-max-frequency: maximal bus speed, should be set something under or equal
10000000
- reg: the chipselect index
- interrupts: the interrupt generated by the device.
Example:
mrf24j40ma@0 {
compatible = "microchip,mrf24j40ma";
spi-max-frequency = <8500000>;
reg = <0>;
interrupts = <19 8>;
interrupt-parent = <&gpio3>;
};
