+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: clock specifiers (refer to the clock binding); two clocks
There should be a phandle preceding the clock specifier, all new such
props are different to the old "interrupts" (which had phandle in a separate
"interrupt-parent" prop).
I'm afraid I don't understand - could you point me to an example?
Have you read Documentation/devicetree/bindings/clock/clock-bindings.txt,
on clock consumers?
In fact, your own example below doesn't have clock specifiers, only phandles.
+ must be specified: the functional clock and an external
+ reference clock
+
+Example:
+
+ sata: sata@4a140000 {
+ compatible = "ti,dm816-ahci";
+ reg = <0x4a140000 0xffff>;
[...]
+ interrupts = <16>;
+ clocks = <&sysclk5_ck>, <&sata_refclk>;
+ };
