2021-11-17regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is ↵Krzysztof Kozlowski
disabled commit b16bef60a9112b1e6daf3afd16484eb06e7ce792 upstream. The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

During reset the VMMC regulator doesn't reach 0V and only drops to 1.8V, furthermore the pulse width is under 200us whereas the SD specification expect 1ms. For this 2 reasons being able to no reset at all the VMMC during warm reset and keep the current voltage is a good workaround. The TWL6030 allows this but needs to be aware of it and this configuration should also be shared with the bootloader.

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.
