Hi Heiko,
After check the software i2c code, I found it can not support multi
instances, although it has I2C_SOFT_DECLARATIONS2,
I2C_SOFT_DECLARATIONS3, I2C_SOFT_DECLARATIONS4.
Because, when do GPIO operation, there is only one pair of
CONFIG_SOFT_I2C_GPIO_SCL and CONFIG_SOFT_I2C_GPIO_SDA.
So, if want to support multi instances, it needs to extend the GPIO
configuration for SCL/SDA, am I right?
Thanks.
Best Regards,
Bo Shen
