[PATCH v2 0/5] Add peripheral nodes to RaspberryPi 5 DT

[PATCH v2 0/5] Add peripheral nodes to RaspberryPi 5 DT

[Andrea della Porta]

Hi,

The following patches add a few peripheral DT nodes and related pin/gpio
nodes for Raspberry Pi 5.

- Patch 1: Amend the bindings to avoid DT compiler warnings.

- Patch 2: Adds core pinctrl nodes and defines SD pins as a first appliance
  for the pinctrl.  

- Patch 3: Wires the gpio-key for power button and related gpio controller.

- Patch 4: Adds DT node for WiFi.

- Patch 5: Adds Bluetooth DT node.

All comments and suggestions are welcome!

Happy hacking!
Ivan and Andrea


CHANGES in V2:

--- DTS ---

- bcm2712.dtsi: added a proper clocks node to the uarta serial
  in order to replace the legacy clock-frequency property. As
  a result, the following patch from the previous patchset
  has been dropped since it's now useless:

  "dt-bindings: serial: Add clock-frequency property as an alternative to clocks"


Andrea della Porta (1):
  dt-bindings: mmc: Add support for capabilities to Broadcom SDHCI
    controller

[PATCH v2 1/5] dt-bindings: mmc: Add support for capabilities to Broadcom SDHCI controller

[Andrea della Porta]

The Broadcom BRCMSTB SDHCI Controller device supports Common
properties in terms of Capabilities.

Reference sdhci-common schema instead of mmc-controller in order
for capabilities to be specified in DT nodes avoiding warnings
from the DT compiler.

[Andrea della Porta]

From: "Ivan T. Ivanov" <iivanov@suse.de>

Add SDIO2 node. On RPi5 it is connected to WiFi chip.
Add related pin, gpio and regulator definitions and
add WiFi node. With this and firmware already provided by
distributions, at least on openSUSE Tumbleweed, this is
sufficient to make WiFi operational on RPi5 \o/.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250828 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

For some reason I've dropped, from the previous cover letter, the
phrase mentioning that this patchset depends on this patchset:

https://lore.kernel.org/all/7ed0f2779829f4e63b69d8cf5cedda9f849996bc.1756372805.git.andrea.porta@suse.com/

which contains the schema. If you apply it as prerequisite, warnings
should disappear.

Many thanks,
Andrea
