Hello,

I am running bootstrap on sama5d3 (sorry a bit newbie on sama chips).

It turns out I want to disable i2C interface of PMIC.

The option is enabled by default, but when debugging, the workaround does not detect pmic and does nothing, but later, my pmic work well in kernel, to much well that I want to disable it interface because interferring with my touch panel.

Sorry, It seems my I2C bus was in trouble in hardware, no external pull up drove the bus crazy and not working well
