    1 EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices
    2 
    3 Required 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 
   22 Optionally 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 
   31 Example:
   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         };
