So this patch series pass signal voltage to the controller specific ->voltage_switch() callback. Adds controller specific configuration for other voltages as well, and add implementation for ->voltage_switch to pxav3 driver. Note: Currently ->voltage_switch() callback is only supported in f_sdh30 driver. And I am not sure on the dependency of execution sequence for that device. I could have moved ->voltage_switch() call at one common place (above/below), but was not quite sure about it. So, replicated/duplicated the call for other voltages.
