Subject: [PATCH 1/2] arm64: dts: Add a device tree for the Librem5 phone

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.

hi,

I highly appreciate it in case you can take time to review. It's not the
smallest board, but this "base" support isn't huge either. For
devicetree people this is certainly easy to read and I'll be happy for
any opinions, objections or Acks you might have.

thanks,

martin

Nit: I would add the wakeup-source behind the linux,code.

Why should this regulator be always on? The wm8962.c driver can handle
the regualtor enable/disable.

Is it intended to use capitalized and no-capitalized regulator-name's?

Can we squash regulator-audio-pwr-en and regulator-audio-v1v8?

This regulator is never used.

Either I would bundle all clock settings here or within the sai nodes.

Missmatch with the pinctrl_ecspi1?

Out of curiosity, why did you marked all regulators as
regulator-always-on? I thought the librem5 is a smartphone.

You need to mux the irq gpio.

irq-gpios is not supported by the driver. We only have a
wake/reset-gpio.

Please check that "reg" is always the 2nd property after the
"compatible".

The compatible should be "ti,bq25895" if it is a bq25895. So we can drop
the comment too.

I would only mention the units within a comment because comments like
this begin to divergence after you fix something.

Is it okay to take care of all imx8mq-librem5* files?

Droid 4 uses "status-led:{red,green,blue}". Could this use same
naming?

This is one LED, right? I'm pretty sure we don't want lm3560 in the
name... "main-camera:flash" would be better. Even better would be
something that's already in use.

> + label = "white:backlight_cluster";

Make this ":backlight", please. Again, we want something that's
already used.

Best regards,

Hi!

Plus, do we need calibration matrix for magnetometer?

I guess so. It's not a calibration matrix, it's the mount matrix that
tells you how the chip is placed on the PCB relative to a "natural"
orientation, see

Looking at leds-class.rst we don't have a useful devicename so
should that just be omitted and s.th. like

label = "blue:status";
label = "green:status";
label = "red:status";

be used instead. If we want to map to current usage

label = "blue:status";
label = "green:boot";
label = "red:charging";

would be even closer but since that is bound to change just going with
"status" would make sense.
Cheers,

It can indeed be handled by the driver here. We keep it always on
because of issues with the display stack that are not yet part of this
description.

It is. But we just currently see an unstable system in case we allow
turning most of them off. We do for the VPU, and should (afaik already)
be able to do so for the GPU. After more work in the drivers the mipi
regulator(s) should be able to be turned off. So we'll look at more and
more of these over time.
