0ae0cb7b50 dm: sf: Add tests for SPI flash
Add a simple test for SPI that uses SPI flash. It operates by creating a
SPI flash file and using the 'sf test' command to test that all
operations work correctly.

ebcab48a03 dm: spi: Add tests
These tests use SPI flash (and the sandbox emulation) to operate.

1ca7e2062b dm: Provide a function to scan child FDT nodes
At present only root nodes in the device tree are scanned for devices.
But some devices can have children. For example a SPI bus may have
several children for each of its chip selects.

Add a function which scans subnodes and binds devices for each one. This
can be used for the root node scan also, so change it.

A device can call this function in its bind() or probe() methods to bind
its children.

b6a49a7ae7 dm: Allow driver model tests only for sandbox
The GPIO tests require the sandbox GPIO driver, so cannot be run on other
platforms. Similarly for the 'dm test' command.

0681195977 dm: Add a 'dm' command for testing
This command is not required for driver model operation, but can be useful
for testing. It provides simple dumps of internal data structures.

2e7d35d2a6 dm: Add basic tests
Add some tests of driver model functionality. Coverage includes:

- basic init
- binding of drivers to devices using platform_data
- automatic probing of devices when referenced
- availability of platform data to devices
- lifecycle from bind to probe to remove to unbind
- renumbering within a uclass when devices are probed/removed
- calling driver-defined operations
- deactivation of drivers when removed
- memory leak across creation and destruction of drivers/uclasses
- uclass init/destroy methods
- automatic probe/remove of children/parents when needed

This function is enabled for sandbox, using CONFIG_DM_TEST.
