Frequency

Node format

Offset	Size	Description
0	1	type = 0x0d
1	1	flags = 0
2	2	parent node
4	4	divisor
8	8	clock frequency

Lot of devices specify frequency in terms of a clock frequency and a divisor. You can attach this node to such devices. If div is zero, then no divisor is used and base is the absolute frequency in milliHz (so base of 1000 = 1 Hz).
