I don't think these last 2 make sense. turbo-mode is a flag that the mode has restrictions such as other cores have to be idle or something. Similarly, opp-suspend should not vary by <name>.
Based on what version of the hardware you are running, via opp-supported-hw property, the platform can enable a different set of OPPs. And in that case we may want to select different OPPs marked as turbo or suspend freq. That's what I thought at least.
For example, on version A of the hardware we have following available frequencies: 800, 1000, 1100, 1200 MHz. Where 800 MHz is the suspend freq and 1200 is the turbo one.
But on a slightly different version of hardware B, we have two more OPPs available: 700 and 1400 MHz. And in that case we want the suspend freq to be 700 and turbo OPP to be only 1400 MHz.
