I2C Address Mapping; Table 3: Gpio Mapping (Tps65950) - Mistral OMAP35 Series Hardware User's Manual

Note:
1
LOCK - R56 is not mounted on the OMAP processor module by default
and hence NAND lock functionality is disabled.
POP_INT03
module by default and hence this signal (INT) is not connected to
GPMC_nCS2/GPIO_53.
DDR_TEMP_SENSE
module by default and hence DDR temp sense is disabled.
If the user wants to enable the feature, corresponding resistors need to
be mounted.

I2C Address Mapping

The communication between the Processor and the TPS65950 device is
established through the I2C1 interface. The TPS65950 has four I2C address
groups. Each I2C address group allows access to a 256-byte register address
map.
I2C2 of OMAP3530 is being shared across camera modules. Also it is routed to
expansion connector
I2C3 of OMAP35x is connected to Video decoder as a control interface. Also it is
routed to expansion connector
The register addressing for I2C interface is given below:
- Resistor R56 is NOT mounted on the OMAP processor
2
- Resistor R2 is not mounted on the OMAP processor
