Dear Simon Glass,
As an example of how to write a uclass and a driver, provide a demo version of each, accessible through the 'demo' command.
To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO.
The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and CONFIG_DM_DEMO_SHAPE.

Changes in v3:
- Fix up demo command help
- Update demo driver to use device tree
Changes in v2: None
[...]
+U_BOOT_DEVICE(demo4) = {
- .name = "demo_shape_drv",
- .platform_data = &yellow_hexagon,
+};
So this is static instantiation of the drivers?
[...]
+U_BOOT_DRIVER(demo_simple_drv) = {
- .name = "demo_simple_drv",
- .of_match = demo_shape_id,
- .id = UCLASS_DEMO,
- .probe = demo_shape_probe,
- .ops = &simple_ops,
- .ops = &simple_ops,
This .ops is here twice ;-)
- .platform_data_auto_alloc_size = sizeof(struct dm_demo_pdata),
+};
[...]
