Those nodes are designated as clock providers. Clock consumer nodes use a phandle and clock specifier pair to connect clock provider outputs to clock inputs. Similar to the gpio specifiers, a clock -specifier is an array of one more more cells identifying the clock +specifier is an array of zero, one or more cells identifying the clock output on a device. The length of a clock specifier is defined by the value of a #clock-cells property in the clock provider node. diff --git a/Documentation/devicetree/bindings/net/macb.txt b/Documentation/devicetree/bindings/net/macb.txt index 4ff65047bb9a..70af2ec12b09 100644 --- a/Documentation/devicetree/bindings/net/macb.txt +++ b/Documentation/devicetree/bindings/net/macb.txt @@ -10,6 +10,10 @@ Required properties: - interrupts: Should contain macb interrupt - phy-mode: String, operation mode of the PHY interface.
