(arch/arm/mach-davinci/pm_domain.c) I agree with Grygorii. Calling this clock "fck" will make it easy to convert the DA850 AHCI driver to use pm_runtime at a future date (no mach-davinci changes should be needed). Sorry about not spotting this earlier.

The ahci-da850 SATA driver is now capable of retrieving clocks by con_id. Add the connection id for the sysclk2-derived SATA clock.
