Add CPLD class for Mihawk platform If PGOOD signal is abnormal when chassis power_on, read Mihawk's CPLD-register via I2C to confirm the error. First, confirm whether the power_on_error signal is 1 when chassis power_on(1 means abnormal). If the signal is 1, read the error-code-register to analysis reason. Second, runtime to confirm whether the power_ready_error signal is 1 after chassis power_on(1 means abnormal). If the signal is 1, read the error-code-register to analysis reason and shutdown the chassis. Tested: Use command "obmcutil chassiskill" to trigger PGOOD error action analysis during chassis power on.

Code for detecting and analyzing power faults on Witherspoon.
To build this package, do the following steps: 1. meson build 2. ninja -C build To clean the repository again run `rm -rf build`.
Several applications in this repository require a PSU JSON config to run. The JSON config file provides information for:
There is an example psu.json to describe the necessary configurations.
inventoryPMBusAccessType
defines the pmbus access type, which tells the service which sysfs type to use to read the attributes. The possible values are:/sys/bus/i2c/devices/3-0069/
/sys/bus/i2c/devices/3-0069/hwmon/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/cffps1/
fruConfigs
defines the mapping between the attribute file and the FRU inventory interface and property. The configuration example below indicates that the service will read part_number
attribute file from a directory specified by the above pmbus access type, and assign to PartNumber
property in xyz.openbmc_project.Inventory.Decorator.Asset
interface."fruConfigs": [ { "propertyName": "PartNumber", "fileName": "part_number", "interface": "xyz.openbmc_project.Inventory.Decorator.Asset" } ]
psuDevices
defines the kernel device dir for each PSU in inventory. The configuration example below indicates that powersupply0
's device is located in /sys/bus/i2c/devices/3-0069
."psuDevices": { "/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply0" : "/sys/bus/i2c/devices/3-0069", }
