+STMicroelectronics STM32 Factory-programmed data device tree bindings
+
+This represents STM32 Factory-programmed read only non-volatile area: locked
+flash, OTP, read-only HW regs... This contains various information such as:
+analog calibration data for temperature sensor (e.g. TS_CAL1, TS_CAL2),
+internal vref (VREFIN_CAL), unique device ID...
+
+Required properties:
+- compatible: Should be one of:
+ "st,stm32f4-otp"
+ "st,stm32mp15-bsec"
+- reg: Offset and length of factory-programmed area.
+- #address-cells: Should be '<1>'.
+- #size-cells: Should be '<1>'.
+
+Optional Data cells:
+- Must be child nodes as described in nvmem.txt.
+
+Example on stm32f4:
+ romem: nvmem@1fff7800 {
+ compatible = "st,stm32f4-otp";
+ reg = <0x1fff7800 0x400>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* Data cells: ts_cal1 at 0x1fff7a2c */
+ ts_cal1: calib@22c {
+ reg = <0x22c 0x2>;
+ };
+ ...
+ };
