-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
-
-Optional properties:
-- quality : estimated number of bits of true entropy per 1024 bits read from the
- rng. Defaults to zero which causes the kernel's default quality to
- be used instead. Note that the default quality is usually zero
- which disables using this rng to automatically fill the kernel's
- entropy pool.
-
-N.B. currently 'reg' must be at least four bytes wide and 32-bit aligned
-
-Example:
-
-hwrng@44 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "timeriomem_rng";
- reg = <0x44 0x04>;
- period = <1000000>;
