From: "Angus Ainslie (Purism)" <[email protected]>
Add a devicetree description for the Librem 5 phone. 4 hardware revisions
have been available. Some revisions include changes that need different
software to be run. So far, r3 ("Dogwood") is one such example, see:
"Aspen" r0 not supported (very few devices exist)
"Birch" r1 supported by r2
"Chestnut" r2 added by this patch
"Dogwood" r3 added by this patch
"Evergreen" r4 tba / most likely supported by r3
See https://puri.sm/products/librem-5/ for more information.
This boots to a working console with working WWAN modem, wifi usdhc,
IMU sensor device, proximity sensor, haptic motor, gpio keys, GNSS and LEDs.

revision history
----------------
v5:
thanks a lot Pavel for reviewing again
* remove pwmleds (no stable interface yet)
v4:
thanks a lot Shawn for reviewing
* rename to dtsi and split out r2 and r3 dts with revision specifics
* add the USB2642 hard-wired Hub
* fix charge controller boost-max-current
* disable pullup on CHRG_INT (not needed due to external one)
* add documentation for the boards' compatible strings
* fix led-backlight propery usage
* coding style fixes

v3:
thanks a lot Mark for reviewing! changes since v2:
* nicer audio cards names
* squash unneeded audio_pwr regulator
* remove the susphy_quirk from dwc3_1 after more testing
* add usdhc2 card detect via gpio
* add headphone detect for audio card

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
* audio clk settings moved to sai2 node

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.
If a tag was not added on purpose, please state why and what changed.

I'm very sorry. I forgot to add to this patch:
Acked-by: Rob Herring <[email protected]>
It was not done on purposes and I'll add it to a next series and equally
hope that this note would make a maintainer add it in case this series
turns out to be ready.
thanks for the explanation and again, sorry.

hi Shawn, hi all,
the merge window is basically over and maybe you'll then find time to
review whether you still find problems with this addition. In case
you've looked at an older version of this, all changes should be listed
in the revision history above.
thanks again,
martin
Hi Martin,
This looks good.
Only some minor comments:

Please pass pinctrl-names = "default"; prior to pinctrl-0. Please
check globally in this patch.

This should be active low instead.
After 8cdcd8aeee28 ("spi: imx/fsl-lpspi: Convert to GPIO descriptors")
you should a similar message as in the kernel log:
flash@0 enforce active low on chipselect handle

This seems to be not documented. It also misses the vendor.

Remove the comment, maybe?
