The Librem5 devkit is based on the imx8mq from NXP. This is a default
devicetree to boot the board to a command prompt.
Changes since v3:
Freshly sorted and pressed nodes.
Change the backlight to an interpolated scale.
Dropped i2c2.
Dropped devkit version number to match debian MR.
Changes since v2:
Fixed incorrect phy-supply for the fsl-fec.
Dropped unused regulator property.
Fixup Makefile for linux-next.
Changes since v1:
Dropped config file.
Updated the board compatible label.
Changed node names to follow naming conventions.
Added a more complete regulator hierachy.
Removed unused nodes.
Removed unknown devices.
Fixed comment style.
Dropped undocumented properties.

support yields a working console and is able to boot userspace from the
Network or eMMC.
Additional subsystems that are active :
- Both USB ports
- SD card socket
- WiFi usdhc
- WWAN modem
- GNSS
- GPIO keys
- LEDs
- gyro
- magnetometer
- touchscreen
- pwm
- backlight
- haptic motor
