Add support for the on-board SATA controller present on TI DM816 SoCs.
This IP suffers from the same issue DA850 does, that is: if we enable
PMP, but connect the drive directly to the board, the disk cannot be
detected. A workaround similar to the one implemented in ahci-da850 is
included in this driver as well.
Tested on DM8168-EVM.
v1 -> v2:
PATCH 1/2
- fixed the size of the mapped register region in the example
- rephrased the clocks property description
