This adds initial device tree support for the following phones:

 - Google Pixel 3 (blueline)
 - Google Pixel 3 XL (crosshatch)

Both phone boards use the same identifiers and differ only slightly
in their connected peripherals.

Supported functionality includes:
 - Debug UART
 - UFS
 - Charger
 - USB-C (peripheral mode)
 - Display (Pixel 3 only)

This is mainly focused to get the base functionality of the board and
being able to use the upstream DTS within Linux and u-boot.

Booting
-------
For older Pixel 3 bootloaders, bootloader-compatible board and MSM IDs are
required for the kernel to boot, so these have been added.

For recent Pixel 3 bootloaders,
a) you want chainloaded proper bootloader (f.e. u-boot),
b) you can also boot kernel when adding back TEXT_OFFSET
   (partial revert of 120dc60d).

This series is a beggining of cleaning up and transitioning support from
sdm845 close to mainline tree to the mainline.

This adds initial device tree support for the following phones:

 - Google Pixel 3 (blueline)
 - Google Pixel 3 XL (crosshatch)

Both phone boards use the same identifiers and differ only slightly
in their connected peripherals.

Supported functionality includes:
 - Debug UART
 - UFS
 - Charger
 - USB-C (peripheral mode)
 - Display (Pixel 3 only)

GPIOs 0–3 and 81–84 are not accessible from the application CPUs,
so they are marked as reserved to allow the Pixel 3 to boot.

The rmtfs region is allocated using UIO, making it technically "dynamic."

Its address and size can be read from sysfs:

$ cat /sys/class/uio/uio0/name
/sys/class/uio/uio0/maps/map0/addr
0x00000000f2701000

$ cat /sys/class/uio/uio0/maps/map0/size
0x0000000000200000

Like the OnePlus 6, the Pixel 3 requires 1 kB of reserved memory on either
side of the rmtfs region to work around an XPU bug that would otherwise
cause erroneous violations when accessing the rmtfs_mem region.

Please, ignore the panel and display related nodes. I accidentally 
sneaked the WIP parts somehow into the upstream commit. Only framebuffer 
works on the Pixel 3 XL. In next version these nodes will be gone for 
the initial inclusion.

Great to finally see it being submitted!

No remoteprocs / IPA / GPU / Venus / WiFi / BT? The firmware is
accessible to download from Google and it can be further repackaged (but
not redistributed). See [1], [2].

The phones share all firmware except for the bdwlan, so hopefully you
can add 'Google/blueline/foo.mbn' to the common file.

Are these two actually used by the panel? I think they were only used
for sw43402, but not for sw43408.

These are all the same as the -blueline. Please move common options to
the -common.dtsi

More and more common properties. Please move them to the common file.

- Why do you need spiflash here?
- I don't think this uses pmgpios too.

Maybe I should send a patch fixing the TEXT_OFFSET. Let's see what kind
of reaction will it get.

I did purposefully base on 6.17 (and sadly the downgrade from next 
brought this mess), because the support for Pixel 3 is a bit fragile and 
as I have only Pixel 3 XL at home (not the Pixel 3, which I always 
asking someone else to borrow or test for me), I decided to kept 6.17 
base so I know it's the state where blueline boots (in case sdm845 or 
blueline gets broken in the -next).

If you want me to, I can base the next version on -next.

-next currently contains changes from the past ~3 months, which
you're missing out on

You unfortunately have to rebase, or your patches will simply
generate merge conflicts

Anyway, they should not be changed in this patch.

Sounds like your panel driver is not sequencing things properly

Does the phone actually have something connected to both USB hosts?

Would that be the weasel(?) security chip?

I'm sure you can push some of this into -common

Since I didn't have Pixel 3 at hand to test (I sent the series when 
attending event where someone had Pixel 3 ;-) ), I was aiming to merge 
MVP.. more precisely, Minimal Viable Device-tree (MVD).

Until the end of the month I should have also Pixel 3, so I'll 
definitely continue to enable all the mentioned features, but as this 
DTB is also needed for u-boot [1], I would prefer to get MVD in ASAP, 
mostly because of the fastboot is useless for loading mainline kernel.

[1] https://gitlab.postmarketos.org/tauchgang

Before I'll send the v2, the progress can be tracked in
   https://gitlab.com/dhxx/linux/-/commits/b4/pixel-3

Thank you both for the review!
David

Yes, screen and battery.

Would it be acceptable to use path format qcom/sdm845/$codename/ e.g. 
qcom/sdm845/blueline as it's used elsewhere?

As I'm looking at the Google scripts, I assume both blueline/crosshatch 
use same firmware (which makes sense, as only the battery and display is 
different).

Yes, I tested and it seems the display behaves same way.>

Can you clarify, all other device-tree use this format, do you mean 
regulator-pwr-vph?

Thank you

For now, the peripheral usb works, haven't tried to switch to host mode yet.

I assume not,

Bus 001 Device 001: ID 1d6b:0002 Linux 6.16.7-sdm845 xhci-hcd xHCI Host 
Controller
Bus 002 Device 001: ID 1d6b:0003 Linux 6.16.7-sdm845 xhci-hcd xHCI Host 
Controller

I looked at the downstream description and it seems usb_2 was used only 
on sda845 devkit.

We have settled on qcom/SoC/Vendor/device/ long ago. Could you please
follow? All upstream Qualcomm devices follow this approach.

bdwlan should be sent to ath10k ML:
https://wireless.docs.kernel.org/en/latest/en/users/drivers/ath10k/boardfiles.html

Sure, in next version it's done! Would you be open if I sent changes to 
the existing firmware paths for sdm845 firmwares?
