| 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>; |
| }; |
| ... |
| }; |
