[PATCH v5 00/10] DTS updates for system1 BMC

[PATCH v5 00/10] DTS updates for system1 BMC

[Ninad Palsule]

Hello,

Please review the patch set version 5.

V5:
---
  - Improved IPBM device documentation.
  - Added the hog parsing in ast2400-gpio

V4:
---
  - Removed "Add RGMII support" patch as it needs some work from the
    driver side.
  - Improved IPBM device documentation.
  - There is a new warning in CHECK_DTBS which are false positive so
    ignored them.
    arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-system1.dtb: gpio@1e780000: 'hog-0', 'hog-1', 'hog-2', 'hog-3' do not match any of the regexes: 'pinctrl-[0-9]+'

V3:
---
  - Fixed dt_binding_check warnings in ipmb-dev.yaml
  - Updated title and description in ipmb-dev.yaml file.
  - Updated i2c-protocol description in ipmb-dev.yaml file.

V2:
---
  Fixed CHECK_DTBS errors by
    - Using generic node names
    - Documenting phy-mode rgmii-rxid in ftgmac100.yaml
    - Adding binding documentation for IPMB device interface

+title: The Intelligent Platform Management Bus(IPMB) Device
+
+description: |
+  The IPMB is an I2C bus which provides interconnection between a Baseboard
+  Management Controller(BMC) and chassis electronics. The BMC sends IPMI
+  requests to intelligent controllers like Satellite Management Controller(MC)
+  devices via IPMB and the device sends responses back to the BMC.
+  This device uses an I2C slave device to send and receive IPMB messages,
+  either on a BMC or other MC. A miscellaneous device provices a user space
+  program to communicate with the kernel and the backend device. Some IPMB
+  devices only support the I2C protocol and not the SMB protocol.

I am not seeing any error even after upgrading dtschema. Also this mail 
also doesn't show any warning. Is this false negative?

I believe this happens when a prior patch in the series has an error.

Choose one - suffix or prefix. More popular is suffix.

I was about to say that, but this matches what gpio-hog.yaml defines. 
Why we did both, I don't remember. We could probably eliminate 
'hog-[0-9]+' as that doesn't appear to be used much.

Long term, I want to make all gpio controllers reference a gpio 
controller schema and put the hog stuff there. Then we have the node 
names defined in 1 place.

Only one case:
arch/arm64/boot/dts/nvidia/tegra210-p2894.dtsi:                 hog-0 {

Although there are few "hog" prefixes followed by alphanumeric, so not
matching above pattern.

This. The second part of pattern.

I'll send a patch for dtschema to drop the prefix version.

[PATCH v5 08/10] ARM: dts: aspeed: system1: Remove VRs max8952

[Ninad Palsule]

Removing voltage regulators max8952 from device tree. Those are fully
controlled by hardware and firmware should not touch them.

[PATCH v5 09/10] ARM: dts: aspeed: system1: Mark GPIO line high/low

[Ninad Palsule]

- Mark following GPIO lines as input high:
  - GPIOL4 (reset PCH registers)
  - GPIOL5 (reset portition of intel ME)
- Mark isolate errors from cpu1 gpio (GPIOO6) as active low output.
- The fan controller reset line should be active high.

[PATCH v5 10/10] ARM: dts: aspeed: system1: Disable gpio pull down

[Ninad Palsule]

Disable internal pull down for the following GPIO lines.
- GPIOL4 - Reset PCH registers in the rtc.
- GPIOL5 - Reset portition of Intel ME
- GPIOL6 - FM smi active
- GPIOL7 - psu all dc power good.

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
