- 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";
- };
- };
- };
