Subject: [PATCH] dm: test: Add test case for
|
||
|
|
dev_phys_to_bus()/dev_bus_to_phys()
|
||
|
|
|
||
|
|
By reusing DT nodes already available in sandbox's test DT introduce a
|
||
|
|
test to validate dev_phys_to_bus()/dev_bus_to_phys().

Changes since v3:
|
||
|
|
- Use ut_assertok() instead of ut_assert(!func())
|
||
|
|
- Use ut_assert_addr()
