Broadcom OTP memory controller
Required Properties:
- compatible: "brcm,ocotp" for the first generation Broadcom OTPC which is used
in Cygnus and supports 32 bit read/write. Use "brcm,ocotp-v2" for the second
generation Broadcom OTPC which is used in SoC's such as Stingray and supports
64-bit read/write.
- reg: Base address of the OTP controller.
- brcm,ocotp-size: Amount of memory available, in 32 bit words
Example:
otp: otp@0301c800 {
compatible = "brcm,ocotp";
reg = <0x0301c800 0x2c>;
brcm,ocotp-size = <2048>;
};
