I need one of the PWM’s of the i.MX6 to drive the LVDS_CONTRAST signal for the back light of my LCD. Looking at the schematic, it shows it is connected to the PMIC_GPIO11 signal. That signal comes from the PMIC (I believe). How to I control that signal from the i.MX6. I do not have and could not find any information on how the PMIC was connected to the i.MX6.

Shared I2C Bus
The screenshot below shows how the I2C bus (I2C2) is used on ConnectCore 6 module. The bus is shared between
i.MX6 processor and the PMIC/MCA microcontroller.
The ConnectCore 6 Hardware Reference Manual mentioned above, is now located at https://www.digi.com/resources/documentation/digidocs/90001394/default.htm.
