- I2C protocol implementation.
-
- General Description:
-
- The I2C protocol is used for the temperature sensors and for
- the serial EEPROM which hold the configuration.
-
- This file covers functions that allow to read write and do
- some bulk requests a specified I2C address.
-
- The Genesis has 2 I2C buses. One for the EEPROM which holds
- the VPD Data and one for temperature and voltage sensor.
- The following picture shows the I2C buses, I2C devices and
- their control registers.
-
- Note: The VPD functions are in skvpd.c

-. +--------+ +--------+ +----------+
-.
- The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
- and B2_I2C_DATA registers.
- For driver software it is recommended to use the I2C control and
- data register, because I2C bus timing is done by the ASIC and
- an interrupt may be received when the I2C request is completed.
-
- Clock Rate Timing: MIN MAX generated by
- VPD EEPROM: 50 kHz 100 kHz HW
- LM80 over I2C Ctrl/Data reg. 50 kHz 100 kHz HW
- LM80 over B2_I2C_SW register 0 400 kHz SW
-
- Note: The clock generated by the hardware is dependend on the
- PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
- clock is 50 kHz.
