   3 Required properties:
   4   - compatible : should be "<manufacturer>,<type>"
   5                  Basically there is only one manufacturer: idt, but some

  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         };
