These devices support I2C-based access to both 15 memory and a system area that controls authentication and configuration. 16 They expose two I2C addresses, one for the system parameter sector and 17 one for the EEPROM. 18 19allOf: 20 - $ref: /schemas/nvmem/nvmem.yaml# 21 22properties: 23 compatible: 24 enum: 25 - st,m24lr04e-r 26 - st,m24lr16e-r 27 - st,m24lr64e-r 28 29 reg: 30 items: 31 - description: I2C address used for control/system registers 32 - description: I2C address used for EEPROM memory access 33 34required: 35 - compatible 36 - reg 37 38unevaluatedProperties: false 39 40examples: 41 - | 42 i2c { 43 #address-cells = <1>; 44 #size-cells = <0>; 45 46 eeprom@57 { 47 compatible = "st,m24lr04e-r"; 48 reg = <0x57>, /* primary-device */ 49 <0x53>; /* secondary-device */ 50 }; 51 }; 52... 53
