Some boards come with a PMU (system power controller, such as the Ricoh
RN5T618). These need CONFIG_I2C_MESON built-in so the regulators can be
set up during boot.
Also enable CONFIG_PWM_MESON (as module) because some boards use it to
dim the LED and/or generate the 32.768 kHz clock for the SDIO wifi chip.
@Kevin: I assume that you'll take this through your tree, so no immediate
action from the arm-soc maintainers needed, right?

Some boards come with a PMIC (system power controller, for example Ricoh
RN5T618) which is connected through I2C.
Enable the Meson I2C driver so the devices on the I2C bus can be
registered during boot.

This enables the Amlogic Meson PWM controller. It is used for a dimmable
LED on some devices. Additionally some devices use it to generate the
32.768 kHz (low power oscillator) clock.

Correct.
Merged into v4.18/defconfig,
