91945a3d578SAndy Shevchenko	  Intel Calpella platforms support dynamic power sharing between the
92045a3d578SAndy Shevchenko	  CPU and GPU, maximizing performance in a given TDP.  This driver,
92145a3d578SAndy Shevchenko	  along with the CPU frequency and i915 drivers, provides that
92245a3d578SAndy Shevchenko	  functionality.  If in doubt, say Y here; it will only load on
92345a3d578SAndy Shevchenko	  supported platforms.
