[PATCH v2 0/2] Add support for Zyxel EX3510-B

[PATCH v2 0/2] Add support for Zyxel EX3510-B

[Sam Edwards]

Hello BCMBCA maintainers,

This is a second, very minor revision of my previous series for introducing
support for the Zyxel EX3510-B "series," largely motivated by my earlier
patchset [1] that resolves validation errors in the BCMBCA DTs. If checking the
DT, please apply that other patchset first. These changes do not depend on the
other patchset to build correctly or apply cleanly; only to pass validation.

Happy spooky month,
Sam

[1]: https://lore.kernel.org/linux-devicetree/20241009215046.1449389-1-CFSworks@gmail.com/T/

Changes v1->v2:
- Rolled-in commit tags from previous version
- Stylistic change to memory: s/0/0x0
- Delete `range` property from the `nvmem-cells` node, in order to pass DT
  checks.

COMMITTER NOTE: Email being what it is, the capitalization of my email address
is apparently getting discarded. If it is important that the author email
address have identical capitalization to the Signed-off-by, please explain why
so I can investigate why this is happening and/or get these patches to you in a
desired format.

[PATCH v2 1/2] dt-bindings: arm64: bcmbca: Add Zyxel EX3510-B based on BCM4906

[Sam Edwards]

This is a series (EX3510-B0 and EX3510-B1) of residential gateways based
on BCM4906, a stripped-down version of the BCM4908 SoC. Although Zyxel's
marketing materials call this a "series," the EX3510-B1 appears to be a
very minor revision of the EX3510-B0, with only changes that are
transparent to software. As far as Linux is concerned, this "series"
effectively represents a single model.

[PATCH v2 2/2] arm64: dts: broadcom: bcmbca: bcm4908: Add DT for Zyxel EX3510-B

[Sam Edwards]

Zyxel EX3510-B is a WiFi 6 capable home gateway (family) based on the
BCM4906 SoC, with 512MiB of RAM and 512MiB of NAND flash. WiFi support
consists of a BCM6710 and a BCM6715 attached to separate PCIe buses.

Add an initial devicetree for this system, with support for:
- Onboard UART (per base dtsi)
- USB (2.0 only; superspeed devices are treated as high-speed due to an
    unknown cause)
- Both buttons (rear reset, front WPS)
- Almost all LEDs:
  - Power (red/green)
  - Internet (red/green)
  - WAN (green)
  - LAN (green; anode is connected to GPIO 13 so currently
      nonfunctioning)
  - USB (green)
  - WPS button (red/green)
  - Absent in DT: There are 2.4GHz/5.0GHz WiFi status LEDs connected to
      the WiFi chips instead of the SoC.
- NAND flash
- Embedded Ethernet switch
- Factory-programmed Ethernet MAC address

WiFi cannot be enabled at this time due to Linux lacking drivers for
both the PCIe controllers and the PCIe WiFi peripherals.

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
