[PATCHv2] Introduce the CFA-10049 expansion board

[Maxime Ripard]

Hi everyone,

Here is a patchset to introduce the CFA-10049 expansion board to the CFA-10036
module.

This expansion board has a number of ADCs and DACs, stepper drivers, GPIO
expanders, a LCD touchscreen and fans. Support for those will come eventually.

We only support the I2C bus for now, that is used for ADCs behind a i2c muxer
and a GPIO expander.


Thanks,
Maxime

Applied both, thanks.
