From: "Angus Ainslie (Purism)" <[email protected]>
Add a devicetree description for the Librem 5 phone. The early batches
that have been sold are supported as well as the mass-produced device
available later this year, see https://puri.sm/products/librem-5/
This boots to a working console with working WWAN modem, wifi usdhc,
IMU sensor device, proximity sensor, haptic motor, gpio keys, GNSS and LEDs.

----------------
v2:
thanks a lot Marco, Daniel and Pavel for reviewing. changes since v1:
* alphabetical sortings / more consistent node names
* remove unused regulator and pinctrl descriptions
* generic labels for leds, backlight, flash and torch
* regulator names all in caps
* audio clk settings moved to sai2 node
* coding style fixes

This looks broken - a combination of the structure, lack of any
references to reg_audio_pwr_en and the naming suggests that you have one
regulator here for a supply called AUD_1V8 which has a GPIO controlling
the enable. I can't figure out any reason for reg_audio_pwr_en.

You might want to put a more user friendly display name here (eg, one
mentioning Librem 5) - some UIs will show this string to users.
