PLL divider based Dove clocks
Marvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
high speed clocks for a number of peripherals. These dividers are part of
the PMU, and thus this node should be a child of the PMU node.
The following clocks are provided:
ID Clock
-------------
0 AXI bus clock
1 GPU clock
2 VMeta clock
3 LCD clock
Required properties:
- compatible : shall be "marvell,dove-divider-clock"
- reg : shall be the register address of the Core PLL and Clock Divider
Control 0 register. This will cover that register, as well as the
Core PLL and Clock Divider Control 1 register. Thus, it will have
a size of 8.
- #clock-cells : from common clock binding; shall be set to 1
divider_clk: core-clock@0064 {
compatible = "marvell,dove-divider-clock";
reg = <0x0064 0x8>;
#clock-cells = <1>;
};
