0001 EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices
0002
0003 Required properties:
0004 - compatible : should be "<manufacturer>,<type>"
0005 Basically there is only one manufacturer: idt, but some
0006 compatible devices may be produced in future. Following devices
0007 are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2,
0008 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2,
0009 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2;
0010 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a;
0011 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2,
0012 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2,
0013 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2,
0014 89hpes64h16ag2;
0015 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2,
0016 89hpes10t4g2, 89hpes16t4g2, 89hpes16t4ag2, 89hpes5t5,
0017 89hpes6t5, 89hpes8t5, 89hpes8t5a, 89hpes24t6, 89hpes6t6g2,
0018 89hpes24t6g2, 89hpes16t7, 89hpes32t8, 89hpes32t8g2,
0019 89hpes48t12, 89hpes48t12g2.
0020 - reg : I2C address of the IDT 89HPESx device.
0021
0022 Optionally there can be EEPROM-compatible subnode:
0023 - compatible: There are five EEPROM devices supported: 24c32, 24c64, 24c128,
0024 24c256 and 24c512 differed by size.
0025 - reg: Custom address of EEPROM device (If not specified IDT 89HPESx
0026 (optional) device will try to communicate with EEPROM sited by default
0027 address - 0x50)
0028 - read-only : Parameterless property disables writes to the EEPROM
0029 (optional)
0030
0031 Example:
0032 idt@60 {
0033 compatible = "idt,89hpes32nt8ag2";
0034 reg = <0x74>;
0035 #address-cells = <1>;
0036 #size-cells = <0>;
0037
0038 eeprom@50 {
0039 compatible = "onsemi,24c64";
0040 reg = <0x50>;
0041 read-only;
0042 };
0043 };
0044
