[U-Boot] [PATCH V3 0/4] dm: core: add device's uclass platform data and tests

The struct udevice provides two fields for device's platform data:
- .platdata        - to keep platform-dependent data for the device driver
- .parent_platdata - to keep platform-dependent data for the device parent

Some implementations may need addidional platform data, which could be owned
by the uclass. For example, the regulator device's constraints.

This patchset adds the additional field:
- .uclass_platdata - to keep platform-dependend data for the uclass driver

Two tests are added to the test framework:
- one for check dev->uclass_platdata pointer
- second for validation the data assigned to by test uclass's post_bind() method

Change in V2:
- implementation of functions for getting the uclass's device without probe it
- cleanup test code

Change in V3:
- add tests for uclass device get/find functions

Przemyslaw Marczak (4):
  dm: core: add internal functions for getting the device without probe
  dm: core: Extend struct udevice by '.uclass_platdata' field.
  dm: test: Add tests for device's uclass platform data
  dm: test: Add tests for get/find uclass devices
