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; |
|
}; |
|
}; |
