Introduce the `smbios_dev_info` devicetree keyword to specify the instance ID and RefDes (Reference Designation) of onboard devices. Example syntax: device pci 1c.0 on # PCIe Port #1 device pci 00.0 on smbios_dev_info 6 end end device pci 1c.1 on # PCIe Port #2 device pci 00.0 on smbios_dev_info 42 "PCIe-PCI Time Machine" end end The `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` Kconfig option enables using this syntax to control the generated Type 41 entries. When this option is enabled, Type 41 entries are only autogenerated for devices with a defined instance ID. This avoids having to keep track of which instance IDs have been used for every device class. Using `smbios_dev_info` when `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` is not enabled will result in a build-time error, as the syntax is meaningless in this case. This is done with preprocessor guards around the Type 41 members in `struct device` and the code which uses the guarded members. Although the preprocessor usage isn't particularly elegant, adjusting the devicetree syntax and/or grammar depending on a Kconfig option is probably even worse.
