[PATCH v9 0/9] DTS updates for system1 BMC

[PATCH v9 0/9] DTS updates for system1 BMC

[Ninad Palsule]

Hello,

Please review the patch set version 9.

V9:
---
  - Fixed Author name.

V8:
---
  - Updated subject line from bindings to dt-bindings
  - Updated comment with reviewed by.

V7:
---
  - Updated pattern in the ast2400-gpio.yaml
  - Dropped "dt-bindings: net: faraday,ftgmac100" patch sending it
    separately.

V6:
---
  - Fixed dt_binding_check errors for ipmb-dev.yaml
  - Changed the hog parsing pattern in ast2400-gpio

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.
