- * Device specific driver for the EBus i2c devices found on some sun4u

- * Known onboard slave devices on the primary bus are:
- *
- * AXe:
- * 0x40 PCF8574 I/O fan status (CPU fans 1+2)
- * 0x9e PCF8591 A/D temperature (CPU + hotspot)
- *
- * AXmp:
- * 0x70 PCF8574 I/O fan status (fans 1-4)
- * 0x78 PCF8574 I/O fan fail interrupt
- * 0x9a PCF8591 A/D voltage (CPU core)
- * 0x9c PCF8591 A/D temperature (hotspots 1+2, aux. analog 1+2)
- * 0x9e PCF8591 A/D temperature (CPUs 1-4)
- *
- * CP1400:
- * 0x70 PCF8574 I/O reserved for factory use
- * 0x9e PCF8591 A/D temperature (CPU)
- *
- * CP1500:
- * 0x70 PCF8574 I/O reserved for factory use
- * 0x72 PCF8574 I/O geographic address + power supply status lines
- * 0x9e PCF8591 A/D temperature (CPU)
- * 0xa0 AT24C01A hostid
- *
- * For AXmp, CP1400 and CP1500 these are described in more detail in:
