- Third memory resource shall be the host controller
- diagnostic memory resource.
- 4th memory resource shall be the host controller
- AXI memory resource.
- 5th optional memory resource shall be the host
- controller MUX memory resource if required.
-- interrupts : Interrupt-specifier for SATA host controller IRQ.
-- clocks : Reference to the clock entry.
-- phys : A list of phandles + phy-specifiers, one for each
- entry in phy-names.
-- phy-names : Should contain:
