This is simillar as fixed-regulator. Used to extract regulator parent from the device tree. Without that property used, the parent regulator can be shut down (if not an always on). Thus leading to inappropriate behavior: On am62-SP-SK this fix is required to avoid tps65219 ldo1 (SDMMC rail) to be shut down after boot completion.
