Merge tag 'linux-can-next-for-3.16-20140425' of git://gitorious.org/linux-can/linux-can-next
Marc Kleine-Budde says:
====================
this is a pull request of 10 patches for net-next/master.
It consists of three patches by Alexander Shiyan, which improve the
mcp251x driver. Stefano Babic's patch move the SPI driver into a sub
folder. The three patches by Olivier Sobrie add support for the Kvaser
Leaf v2 and usb mini PCIe hardware to the existing driver. Alexander
Stein contributes eg20t support to the c_can pci driver. Together with
the patches on the net-tree, we'll be able to remove the pch_can driver
soon. Kurt Van Dijck's two patches clean up the sysfs attributes of the
softing driver.

+* AT86RF230 IEEE 802.15.4 *
+
+Required properties:
+ - compatible: should be "atmel,at86rf230", "atmel,at86rf231",
+ "atmel,at86rf233" or "atmel,at86rf212"
+ - spi-max-frequency: maximal bus speed, should be set to 7500000 depends
+ sync or async operation mode
+ - reg: the chipselect index
+ - interrupts: the interrupt generated by the device
+
+Optional properties:
+ - reset-gpio: GPIO spec for the rstn pin
+ - sleep-gpio: GPIO spec for the slp_tr pin
+
+Example:
+
+ at86rf231@0 {
+ compatible = "atmel,at86rf231";
+ spi-max-frequency = <7500000>;
+ reg = <0>;
+ interrupts = <19 1>;
+ interrupt-parent = <&gpio3>;
