+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";
|
|
|
+ };
|
|
|
+ };
|
|
