1EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices 2 3Required properties: 4 - compatible : should be "<manufacturer>,<type>" 5 Basically there is only one manufacturer: idt, but some 6 compatible devices may be produced in future. Following devices 7 are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2, 8 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2, 9 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2; 10 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a; 11 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2, 12 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2, 13 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2, 14 89hpes64h16ag2; 15 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2, 16 89hpes10t4g2, 89hpes16t4g2, 89hpes16t4ag2, 89hpes5t5, 17 89hpes6t5, 89hpes8t5, 89hpes8t5a, 89hpes24t6, 89hpes6t6g2, 18 89hpes24t6g2, 89hpes16t7, 89hpes32t8, 89hpes32t8g2, 19 89hpes48t12, 89hpes48t12g2. 20 - reg : I2C address of the IDT 89HPESx device. 21 22Optionally there can be EEPROM-compatible subnode: 23 - compatible: There are five EEPROM devices supported: 24c32, 24c64, 24c128, 24 24c256 and 24c512 differed by size. 25 - reg: Custom address of EEPROM device (If not specified IDT 89HPESx 26 (optional) device will try to communicate with EEPROM sited by default 27 address - 0x50) 28 - read-only : Parameterless property disables writes to the EEPROM 29 (optional) 30 31Example: 32 idt@60 { 33 compatible = "idt,89hpes32nt8ag2"; 34 reg = <0x74>; 35 #address-cells = <1>; 36 #size-cells = <0>; 37 38 eeprom@50 { 39 compatible = "onsemi,24c64"; 40 reg = <0x50>; 41 read-only; 42 }; 43 }; 44 45
