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 v12:
Updated patch to vendor-prefixes.yaml.
Dropped always on from regulators.
Changes since v11:
Added reviewed-by tags.
Fixed subject typo.
Changes since v10:
Moved MAINTAINERS entry to "ARM/FREESCALE IMX" section
Changes since v9:
Added a MAINTAINERS entry for arm64 imx devicetree files.
Changes since v8:
Fixed license comment.
Changed regulators to all lower case.
Changed clock frequency for NXP errata e7805.
Dropped blank line.
Changes since v7:
More regulators always on for USB.
Add vbus regulator.
Drop vbat regulator.
Replace legacy "gpio-key,wakeup" with "wakeup-source".
Add vbus-supply to get rid of warning
imx8mq-usb-phy 382f0040.usb-phy: 382f0040.usb-phy supply vbus not found,
using dummy regulator
Changes since v6:
Dropped unused regulators.
Fix regulator phandles case.
Dropped extra whitespace.
Changes since v5:
Added reviewed-by tags.
Moved USB port links to USB controller node.
Changes since v4:
Compiled against linux-next next-20190415.
Added imx8mq to the arm yaml file.
Re-arrange regulator nodes to drop undefined supplies.
Additional ordering for aesthetics.
Split some long lines.
Added lots of blank lines.
Moved pinctl muxes to where they are used.
Cleaned out reg defintions from regulator nodes.
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.

This is for the development kit board for the Librem 5. The current level
of 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

This is for the development kit board for the Librem 5. The current level
of 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

You can take a look at N900, that has reasonable interface.

So, what kind of LED do you have, and what color is it? label should probably be something like

I thought precharge is usually something low, because you are not yet sure of battery health...?

Are you sure? Normally systems shut down at 3.2V, 3V or so. Li-ion batteries don't
really like to be discharged _this_ deep.

I wanted to control the haptic with the pwm-vibra driver but
"fsl,imx27-pwm" doesn't seem to respect the PWM_POLARITY_INVERTED flag
so when I start the system the vibrator is full on.
I could use gpio-vibrator but that seemed like a waste when the device
is connected to pwm.
I figured the using the pwm-leds interface was a reasonable compromise
until I had an opportunity to make changes the the imx27-pwm driver.
Thanks

I guess in such case it would be best to leave out this section for
now... or keep it disabled / something. We don't want incorrect device
trees to stick around.

As we don't have a specific use for these yet does it really matter if

Looking into it further Sanyo and Panasonic get over 300 cycles bringing
the NCR18650 down to 2.5V so 2.75V should be fine.
