Matti Vaittinen	f43d1b388f	devicetree: bindings: bd718x7: document HW state related ROHM specific properties ... Add ROHM BD71837 / BD71847 specific device tree bindings for controlling the PMIC shutdown/reset states and voltages for different HW states. The PMIC was designed to be used with NXP i.MX8 SoC and it supports SNVS low power state which seems to be typical for NXP i.MX SoCs. However, when SNVS is used we must not allow SW to control enabling/disabling those regulators which are crucial for system to boot as there is a HW limitation which causes SW controlled regulators to be kept shut down after SNVS reset. Allow setting the SNVS to be used as reset target state and allow marking those regulators which are critical for boot.
