-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>;
- };
- ...
- };
