[PATCH v7 0/7] ARM: dts: aspeed: Add Balcones system

[Eddie James]

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

Changes since v7:
 - Remove un-documented fan properties under max31785 nodes
 - Change fan-x to fan@x in max31790 documentation.

Changes since v5:
 - Add patch to add address and size cells to max31790 document
 - Don't remove address and size cells in max31785 fixes change

Changes since v4:
 - Add patch to fix max31785 warnings
 - Add patch to fix missing Bonnell documentation

Changes since v3:
 - Add max31785 to the max31790 document instead of to trivial-devices
 - Fix minor formatting in dps310 document

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

[PATCH v7 4/7] dt-bindings: hwmon: Move max31785 compatibles to max31790 document

The binding for the max31785 is the same as the max31790, so just add
some compatible strings for the max31785 chip.

-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>;

[PATCH v7 5/7] dt-bindings: hwmon: max31790: Use addressed fan nodes

[Eddie James]

Since fan properties can include reg, the fan controller should be
able to specify address-cells and size-cells properties and use
an addressed fan child node.

[PATCH v7 6/7] ARM: dts: aspeed: Add Balcones system

[Eddie James]

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.

Looking at Balcones specifically, there's still an immediate concern:

   /home/andrew/src/kernel.org/linux/origin/build.arm.aspeed_g5/arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-balcones.dtb: pressure-sensor@76 (infineon,dps310): '#io-channel-cells' does not match any of the regexes: '^pinctrl-[0-9]+$'
           from schema $id: http://devicetree.org/schemas/trivial-devices.yaml#

On the whole though it's much cleaner than other IBM devicetrees, just
the DTSI warnings remain. I'd appreciate it if you have some time for
cleanups to Rainier, Everest and Bonnell, the number of warnings is
really quite large :(

Hmm, patch 3 in the series fixes this. Did you apply that one? Here is

Yea, I can try and get to it eventually :)

Indeed.

I hadn't, as I can only take patches 1-2 and 6-7 through the bmc tree.
3 and 4-5 should go through the iio and hwmon trees respectively.

Having tested after integrating the whole series I've applied 1-2 and
6-7 to aspeed/arm/dt.

Thanks,

Andrew
