Some devices (particularly bus devices) must track their children, knowing
when a new child is added so that it can be set up for communication on the
bus.
Add a child_pre_probe() method to provide this feature, and a corresponding
child_post_remove() method.

Aliases are used to provide U-Boot's numbering of devices, such as:
aliases {
spi0 = "/spi@1233";
}
spi@1233 {

}
This tells us that the SPI controller at 1233 is considered to be the
first SPI controller (SPI 0). So we have a numbering for the SPI node.

Devices can have childen that can be addressed by a simple index, the
sequence number or a device tree offset. Add functions to access a child

The index is typically used as a fallback when the sequence number is not

Some device types can have child devices and want to store information

At present only root nodes in the device tree are scanned for devices.

several children for each of its chip selects.

Driver model currently only operates after relocation is complete. In this
