Device tree binding for the TI DM816 AHCI SATA Controller
---------------------------------------------------------
Required properties:
- compatible: must be "ti,dm816-ahci"
- reg: physical base address and size of the register region used by
the controller (as defined by the AHCI 1.1 standard)
- interrupts: interrupt specifier (refer to the interrupt binding)
- clocks: list of phandle and clock specifier pairs (or only
phandles for clock providers with '0' defined for
#clock-cells); two clocks must be specified: the functional
clock and an external reference clock
Example:
sata: sata@4a140000 {
compatible = "ti,dm816-ahci";
reg = <0x4a140000 0x10000>;
interrupts = <16>;
clocks = <&sysclk5_ck>, <&sata_refclk>;
};
