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>;
|
|
};
