Subject: [PATCH v4 0/8] Add support for Pixel 3 and Pixel 3 XL

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.

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.

Until merged, available at:
  https://gitlab.com/sdm845/sdm845-next/-/commits/b4/pixel-3

Changes in v4:
- Updated panel device-tree example to contain the both compatibles.
- Put panel pins into the panel-default-state and drop the suspend state
  as it's not yet used.
- Also, sort the pins. (Konrad)
- Move the framebuffer format to common, as it's UEFI standard. (Konrad)
- Improve commit descriptions and add Fixes tag. (Dmitry)
- Link to v3: https://lore.kernel.org/r/20251118-pixel-3-v3-0-317a2b400d8a@ixit.cz

Changes in v3:
- dropped Documentaion: prefix from 1st commit (Krzysztof)
- Extended the compatible for panel driver.
- Document reserved GPIOs.
- Drop some useless statuses, sort pinctrl. (Konrad)
- Add placeholders for the known i2c devices.
- Link to v2: https://lore.kernel.org/r/20251030-pixel-3-v2-0-8caddbe072c9@ixit.cz

Changes in v2:
- rebased on next-20251030
- generalize chosen to -common (Dmitry)
- demystify rmtfs_mem qcom,vmid
- use qcom,use-guard-pages instead of lower/upper guard block
- merge port@1 endpoint into label mdss_dsi0_out
- sort pinctrl
- sorted the nodes inside root
- put status as a last property into mdss_dsi0 block
- rename volume-keys to gpio-keys   
- removed LS-UART1 label
- removed gmu block, already enabled
- removed accidentally introduced WIP crosshatch panel support
- removed useless panel_pmgpio_pins (Dmitry)
- removed usb_2 as it's unused on production units (only devkit)
- move mdss node into the -common and disable in crosshatch (Dmitry)
- move battery node into the -commonm
- move framebuffer into the -common (Dmitry)
- add all firmwares (Dmitry)
- add Wi-Fi support
- add Bluetooth support
- add missing gpi_dma1 node
- renamed regulators to follow regulator-foo-bar BCP (Dmitry)
- adapt to recent cleanup GPU's zap-shader node
- Link to v1: https://lore.kernel.org/r/20251005-pixel-3-v1-0-ab8b85f6133f@ixit.cz
