+Freescale SAHARA Cryptographic Accelerator included in some i.MX chips.
+Currently only i.MX27 is supported.
+
+Required properties:
+- compatible : Should be "fsl,<soc>-sahara"
+- reg : Should contain SAHARA registers location and length
+- interrupts : Should contain SAHARA interrupt number
+
+Example:
+
+sah@10025000 {
+ compatible = "fsl,imx27-sahara";
+ reg = < 0x10025000 0x800>;
+ interrupts = <75>;

+HWRNG support for the timeriomem_rng driver
+
+Required properties:
+- compatible : "timeriomem_rng"
+- reg : base address to sample from
+- period : wait time in microseconds to use between samples
+
+N.B. currently 'reg' must be four bytes wide and aligned

+ #size-cells = <1>;
