For example: - Buck2, designed for vddarm, should be set to '10b' (ON when PMIC_STBY_REQ = L) since it can be off when `PMIC_STBY_REQ = H` after the kernel enters suspend. - Other bucks remain '01b' (ON when PMIC_ON_REQ = H), matching the default setting. This avoids the need to re-enable them during kernel boot as they are already enabled after PMIC initialization.
