pd_dma_* nodes should be accessible during pre-relocation stage of U-Boot proper for properly handling power domains.
This fixes the issue with permanent failing of invocation of power_domain_get_by_index() in the common code of DM power domain uclass (drivers/power/domain/power-domain-uclass.c).
Fixes: f0cc4eae9a ("core: device: use dev_power_domain_on") Signed-off-by: Igor Opaniuk igor.opaniuk@toradex.com ---
