SMBIOS sysinfo information
==========================
This binding allows the values for the SMBIOS tables to be specified in the
devicetree, as below.
Required properties:
- compatible: "u-boot,smbios" or any other string depending on your board
This driver allows providing board-specific features such as power control
GPIOs. In addition, the SMBIOS values can be specified in the device tree,
as below:
An optional 'smbios' subnode can be used to provide these properties. Within
that, the properties are broken down by table type, as in the System Management
BIOS (Basic Input/Output System) Specification.
Available subnodes for each table type are:
- 1 : system
- 2 : baseboard
- 3 : chassis
Within each subnode the following tables are recognised:
"system" subnode optional properties:
- manufacturer: Product manufacturer for system
- product: Product name
- version: Product version string
- serial: Serial number for system (note that this can be overridden by
the serial# environment variable)
- sku: Product SKU (Stock-Keeping Unit)
- family: Product family
"baseboard" subnode optional properties:
- manufacturer: Product manufacturer for baseboard
- product: Product name
- asset-tag: Asset tag for the motherboard, sometimes used in organisations
to track devices
"chassis" subnode optional properties:
- manufacturer: Product manufacturer for chassis
Example:
sysinfo {
compatible = "sandbox,sysinfo-sandbox";
smbios {
/* Type 1 table */
system {
manufacturer = "Google";
product = "Coral";
version = "rev2";
serial = "123456789";
sku = "sku3";
family = "Google_Coral";
};
/* Type 2 table */
baseboard {
manufacturer = "Google";
product = "Coral";
asset-tag = "ABC123";
};
/* Type 3 table */
chassis {
manufacturer = "Google";
};
};
};
