1HWRNG support for the timeriomem_rng driver
2
3Required properties:
4- compatible : "timeriomem_rng"
5- reg : base address to sample from
6- period : wait time in microseconds to use between samples
7
8Optional properties:
9- quality : estimated number of bits of true entropy per 1024 bits read from the
10            rng.  Defaults to zero which causes the kernel's default quality to
11            be used instead.  Note that the default quality is usually zero
12            which disables using this rng to automatically fill the kernel's
13            entropy pool.
14
15N.B. currently 'reg' must be at least four bytes wide and 32-bit aligned

17Example:
18
19hwrng@44 {
20	#address-cells = <1>;
21	#size-cells = <1>;
22	compatible = "timeriomem_rng";
23	reg = <0x44 0x04>;
24	period = <1000000>;
25};
