Implement sandbox regulator devices for SCMI voltage domains and test them in DM scmi tests.
Signed-off-by: Etienne Carriere etienne.carriere@linaro.org
Changes in v2:
- don't test IS_ENABLED(CONFIG_DM_REGULATOR_SCMI) in test/dm/scmi.c, it's expected enabled when CONFIG_FIRMWARE_SCMI is enabled in sandbox.
