| |
From: Keerthy J <j-keerthy@ti.com>
I2C1 bus is used for the following peripherals P8 connector (MLB) TLV320AIC3106 Audio codec J15 LCD header 24WC256 eeprom TMP102AIDRLT temperature sensor PCF8575 GPIO expander PCA9306 i2c voltage translator -> Goes to P9 for comm interface P2 expansion connector TPS65917 PMIC
The slowest speed of all the peripherals seems to be 400KHz.
