ARM: dts: aspeed: Add Balcones system

The Balcones system is similar to Bonnell but with a POWER11 processor.

Changes since v2:
- Fix a couple of incorrect i2c addresses
- Document dps310 and max31785 properly
- Drop the UCD binding documentation update, it's been fixed

Changes since v1:
- Add all the ucd9000 driver supported compatible strings
- Fix node ordering in Balcones device tree
- Improve commit message to explain addition of ibm-power11-dual.dtsi*** BLURB HERE ***

The DPS310 is a barometric pressure and temperature sensor with an I2C interface. Remove it from trivial-devices.yaml and add it's own documentation.

-Bindings for the Maxim MAX31785 Intelligent Fan Controller
-==========================================================

-Reference:

-https://datasheets.maximintegrated.com/en/ds/MAX31785.pdf
-
-The Maxim MAX31785 is a PMBus device providing closed-loop, multi-channel fan
-management with temperature and remote voltage sensing. Various fan control
-features are provided, including PWM frequency control, temperature hysteresis,
-dual tachometer measurements, and fan health monitoring.
-
-Required properties:
-- compatible     : One of "maxim,max31785" or "maxim,max31785a"
-- reg            : I2C address, one of 0x52, 0x53, 0x54, 0x55.
-
-Example:
-
-        fans@52 {
-                compatible = "maxim,max31785";
-                reg = <0x52>;

I take that back. You already have 'fan' child nodes, so this isn't a trivial device/binding.

Rob

That's true, I will add a proper binding.

Thanks,

Eddie

The Balcones system is similar to Bonnell but with a POWER11 processor. Like POWER10, the POWER11 is a dual-chip module, so a dual chip FSI tree is needed. Therefore, split up the quad chip FSI tree.

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-20250806 (best guess, 5/6 blobs matched)

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