Freescale i.MX21 and i.MX31 SoCs contain a Random Number Generator Accelerator module (RNGA), which is replaced by RNGB and RNGC modules on later i.MX SoC series, the change adds a new compatible property to describe the controller. Since all versions of Freescale RNG modules are legacy, apparently the documentation file has no more potential for further extensions, nevertheless generalize it by removing explicit RNGC specifics.

Freescale RNGA/RNGB/RNGC (Random Number Generator Versions A, B and C)
|
|
|
|
Required properties:
|
|
- compatible : should be one of
|
|
"fsl,imx21-rnga"
|
|
"fsl,imx31-rnga" (backward compatible with "fsl,imx21-rnga")
|
|
"fsl,imx25-rngb"
|
|
"fsl,imx35-rngc"
|
|
- reg : offset and length of the register set of this block
|
|
- interrupts : the interrupt number for the RNG block
|
|
- clocks : the RNG clk source
|
|
|
|
Example:
|
|
|
|
rng@53fb0000 {
|
|
compatible = "fsl,imx25-rngb";
|
|
reg = <0x53fb0000 0x4000>;
|
|
interrupts = <22>;
|
|
clocks = <&trng_clk>;
|
|
};
