Merge branch 'kirkwood/dt' of git://git.infradead.org/users/jcooper/linux into late/kirkwood

From Jason Cooper:

New bindings:
  - iconnect nand and keys
  - mv_cesa
  - gpio-fan

* 'kirkwood/dt' of git://git.infradead.org/users/jcooper/linux:
  ARM: kirkwood: Use devicetree to define DNS-32[05] fan
  hwmon: Add devicetree bindings to gpio-fan
  Crypto: CESA: Add support for DT based instantiation.
  ARM: Kirkwood: Describe iconnect nand in DT.
  ARM: Kirkwood: Describe iconnect keys in DT.

+Bindings for fan connected to GPIO lines
+
+Required properties:
+- compatible : "gpio-fan"
+- gpios: Specifies the pins that map to bits in the control value,
+  ordered MSB-->LSB.
+- gpio-fan,speed-map: A mapping of possible fan RPM speeds and the
+  control value that should be set to achieve them. This array
+  must have the RPM values in ascending order.
+
+Optional properties:
+- alarm-gpios: This pin going active indicates something is wrong with
+  the fan, and a udev event will be fired.
+
+Examples:
+
+	gpio_fan {
+		compatible = "gpio-fan";
+		gpios = <&gpio1 14 1
+			 &gpio1 13 1>;
+		gpio-fan,speed-map = <0    0
+				      3000 1
+				      6000 2>;
+		alarm-gpios = <&gpio1 15 1>;
