* Time Base Generator Clock bindings for Marvell Armada 37xx SoCs
|
||||
|
||||
Marvell Armada 37xx SoCs provde Time Base Generator clocks which are
|
||||
used as parent clocks for the peripheral clocks.
|
||||
|
||||
The TBG clock consumer should specify the desired clock by having the
|
||||
clock ID in its "clocks" phandle cell.
|
||||
|
||||
The following is a list of provided IDs and clock names on Armada 3700:
|
||||
0 = TBG A P
|
||||
1 = TBG B P
|
||||
2 = TBG A S
|
||||
3 = TBG B S
|
||||
|
||||
Required properties:
|
||||
- compatible : shall be "marvell,armada-3700-tbg-clock"
|
||||
- reg : must be the register address of North Bridge PLL register
|
||||
- #clock-cells : from common clock binding; shall be set to 1
|
||||
|
||||
Example:
|
||||
|
||||
tbg: tbg@13200 {
|
||||
compatible = "marvell,armada-3700-tbg-clock";
|
||||
reg = <0x13200 0x1000>;
|
||||
clocks = <&xtalclk>;
|
||||
#clock-cells = <1>;
|
||||
};
