Drivers need to handle !PM case with work arounds for managing clocks and power explicitly, which is not really necessary when PM support on tegra is in good shape. In fact ARM 64-bit tegra platforms enforce PM support and there is no reason why this cannot be done for 32-bit. This patch selects PM unconditionally and drivers can rely on runtime PM framework for clock and power management.
