This series contains all the changes necessary to make SATA work on the da850-lcdk board. The first patch adds a clock lookup entry required for the ahci core to retrieve a functional clock. The second enables relevant config options for all davinci boards. The third adds device tree bindings for the ahci_da850 driver. The fourth adds a workaround for a SATA controller instability we detected after increasing the PLL0 frequency for proper LCD controller support. Patches 5 through 7 extend the ahci_da850 driver - add DT support, un-hardcode the clock multiplier value and add a workaround for a quirk present on the da850 SATA controller. Patches 8-10 add the device tree changes required to probe the driver. I'm posting the series as a whole to give all reviewers the full picture and visibility of the changes required, if needed I can resend the patches separately.
