Hi, Liam & Mark:
seems at present, the set_suspend_voltage() is designed to cover the suspend voltage handling from board level, when the system enters into the suspend; but the behavior of my chip is as following: a) there are two sets of registers to configure one regulator's voltage separately, one is for active mode, the other is for the low power mode, say, suspend-to-ram; b) both of the sets have control bits independently; c) once the low power mode is triggered, by external signal, for example, pull-down a gpio, the regulator switches to use the registers for low power mode; d) the consumers have different requirements for the voltage in low power mode according to different scenario, IOW, we cannot assume a fix value when system boots up;
So do you think it's good to export the set_suspend_voltage()? to make it controllable by the regulator itself? another method in my opinion is add a set of virtual-regulator for this usage?
could you please share your advice?
thanks very much;
