| 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. | |
