Note to future me, and anyone else who's getting the kStatus_LPI2C_ArbitrationLost error when attempting to use the I2C Peripheral.
If you're getting this ArbitrationLost error, with the I2C clock and data pins *only* doing a start condition, then immediately failing, it's likely because you don't have the "SoftwareInputOn' mode selected in the IOMUXC.

Thanks for this. I spent a few hours tracing the issue without success until I found this. It's real easy to overlook stuff when setting up basic peripherals on the i.MX because there is just so much stuff to configure.
