1*4882a593SmuzhiyunPLL divider based Dove clocks
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunMarvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
4*4882a593Smuzhiyunhigh speed clocks for a number of peripherals.  These dividers are part of
5*4882a593Smuzhiyunthe PMU, and thus this node should be a child of the PMU node.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunThe following clocks are provided:
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunID	Clock
10*4882a593Smuzhiyun-------------
11*4882a593Smuzhiyun0	AXI bus clock
12*4882a593Smuzhiyun1	GPU clock
13*4882a593Smuzhiyun2	VMeta clock
14*4882a593Smuzhiyun3	LCD clock
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunRequired properties:
17*4882a593Smuzhiyun- compatible : shall be "marvell,dove-divider-clock"
18*4882a593Smuzhiyun- reg : shall be the register address of the Core PLL and Clock Divider
19*4882a593Smuzhiyun   Control 0 register.  This will cover that register, as well as the
20*4882a593Smuzhiyun   Core PLL and Clock Divider Control 1 register.  Thus, it will have
21*4882a593Smuzhiyun   a size of 8.
22*4882a593Smuzhiyun- #clock-cells : from common clock binding; shall be set to 1
23*4882a593Smuzhiyun
24*4882a593Smuzhiyundivider_clk: core-clock@64 {
25*4882a593Smuzhiyun	compatible = "marvell,dove-divider-clock";
26*4882a593Smuzhiyun	reg = <0x0064 0x8>;
27*4882a593Smuzhiyun	#clock-cells = <1>;
