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.

1Marvell Cryptographic Engines And Security Accelerator
2
3Required properties:
4- compatible : should be "marvell,orion-crypto"
5- reg : base physical address of the engine and length of memory mapped
6 region, followed by base physical address of sram and its memory
7 length
8- reg-names : "regs" , "sram";
9- interrupts : interrupt number
10
11Examples:
12
13 crypto@30000 {
14 compatible = "marvell,orion-crypto";
15 reg = <0x30000 0x10000>,
16 <0x4000000 0x800>;
17 reg-names = "regs" , "sram";
18 interrupts = <22>;
19 status = "okay";
20 };

1Bindings for fan connected to GPIO lines
2
3Required properties:
4- compatible : "gpio-fan"
5- gpios: Specifies the pins that map to bits in the control value,
6 ordered MSB-->LSB.
7- gpio-fan,speed-map: A mapping of possible fan RPM speeds and the
8 control value that should be set to achieve them. This array
9 must have the RPM values in ascending order.
10
11Optional properties:
12- alarm-gpios: This pin going active indicates something is wrong with
13 the fan, and a udev event will be fired.
14
15Examples:
16
17 gpio_fan {
18 compatible = "gpio-fan";
19 gpios = <&gpio1 14 1
20 &gpio1 13 1>;
21 gpio-fan,speed-map = <0 0
22 3000 1
23 6000 2>;
24 alarm-gpios = <&gpio1 15 1>;
25 };
