Document new compatible strings, document the new method to reference the
crypto SRAM and deprecate the old one and document the the 'clocks' and
'clock-names' properties.

Marvell Cryptographic Engines And Security Accelerator
Required properties:
-- compatible : should be "marvell,orion-crypto"
-- reg : base physical address of the engine and length of memory mapped
- region, followed by base physical address of sram and its memory
- length
-- reg-names : "regs" , "sram";
-- interrupts : interrupt number
+- compatible: should be one of the following string
+ "marvell,orion-crypto"
+ "marvell,kirkwood-crypto"
+ "marvell,armada-370-crypto"
+ "marvell,armada-xp-crypto"
+ "marvell,armada-375-crypto"
+ "marvell,armada-38x-crypto"
+- reg: base physical address of the engine and length of memory mapped
+ region
+- reg-names: "regs"
+- interrupts: interrupt number
+- clocks: reference to the crypto engines clocks. This property is not
+ required for orion and kirkwood platforms
+- clock-names: "cesaX" and "cesazX", X should be replaced by the crypto engine
+ id.
+ This property is not required for the orion and kirkwoord
+ platforms.
+ "cesazX" clocks are not required on armada-370 platforms
+- marvell,crypto-srams: phandle to crypto SRAM definitions
+
+Optional properties:
+- marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
+ specified the whole SRAM is used (2KB)
+
+Deprecated properties:
+- reg: base physical address of the engine and length of memory mapped
+ region, followed by base physical address of sram and its memory
+ length
+- reg-names: "regs" , "sram"
Examples:
- crypto@30000 {
- compatible = "marvell,orion-crypto";
- reg = <0x30000 0x10000>,
- <0x4000000 0x800>;
- reg-names = "regs" , "sram";
- interrupts = <22>;
+ crypto@90000 {
+ compatible = "marvell,armada-xp-crypto";
+ reg = <0x90000 0x10000>;
+ reg-names = "regs";
+ interrupts = <48>, <49>;
+ clocks = <&gateclk 23>, <&gateclk 23>;
+ clock-names = "cesa0", "cesa1";
+ marvell,crypto-srams = <&crypto_sram0>, <&crypto_sram1>;
+ marvell,crypto-sram-size = <0x600>;
status = "okay";
