Merge branch 'ieee802154-for-davem-2018-02-26' of git://git.kernel.org/pub/scm/linux/kernel/git/sschmidt/wpan-next
Stefan Schmidt says: ==================== pull-request: ieee802154-next 2018-02-26 An update from ieee802154 for *net-next* Alexander corrected a setting which got lost during some 6lowpan rework a while back and Xue Liu provided us with a new driver for the MCR20A transceiver. If there are any issues let me know. If not, please pull. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

+* MCR20A IEEE 802.15.4 *
+
+Required properties:
+ - compatible: should be "nxp,mcr20a"
+ - spi-max-frequency: maximal bus speed, should be set to a frequency
+ lower than 9000000 depends sync or async operation mode
+ - reg: the chipselect index
+ - interrupts: the interrupt generated by the device. Non high-level
+ can occur deadlocks while handling isr.
+
+Optional properties:
+ - rst_b-gpio: GPIO spec for the RST_B pin
+
+Example:
+
+ mcr20a@0 {
+ compatible = "nxp,mcr20a";
+ spi-max-frequency = <9000000>;
+ reg = <0>;
+ interrupts = <17 2>;
+ interrupt-parent = <&gpio>;
+ rst_b-gpio = <&gpio 27 1>
+ };
