| EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices | |
| Required properties: | |
| - compatible : should be "<manufacturer>,<type>" | |
| Basically there is only one manufacturer: idt, but some | |
| compatible devices may be produced in future. Following devices | |
| are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2, | |
| 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2, | |
| 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2; | |
| 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a; | |
| 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2, | |
| 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2, | |
| 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2, | |
| 89hpes64h16ag2; | |
| 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2, | |
| 89hpes10t4g2, 89hpes16t4g2, 89hpes16t4ag2, 89hpes5t5, | |
| 89hpes6t5, 89hpes8t5, 89hpes8t5a, 89hpes24t6, 89hpes6t6g2, | |
| 89hpes24t6g2, 89hpes16t7, 89hpes32t8, 89hpes32t8g2, | |
| 89hpes48t12, 89hpes48t12g2. | |
| - reg : I2C address of the IDT 89HPESx device. | |
| Optionally there can be EEPROM-compatible subnode: | |
| - compatible: There are five EEPROM devices supported: 24c32, 24c64, 24c128, | |
| 24c256 and 24c512 differed by size. | |
| - reg: Custom address of EEPROM device (If not specified IDT 89HPESx | |
| (optional) device will try to communicate with EEPROM sited by default | |
| address - 0x50) | |
| - read-only : Parameterless property disables writes to the EEPROM | |
| (optional) | |
| Example: | |
| idt@60 { | |
| compatible = "idt,89hpes32nt8ag2"; | |
| reg = <0x74>; | |
| #address-cells = <1>; | |
| #size-cells = <0>; | |
| eeprom@50 { | |
| compatible = "onsemi,24c64"; | |
| reg = <0x50>; | |
| read-only; | |
| }; | |
| }; | |
