1NXP LPC32xx Clock Controller
2
3Required properties:
4- compatible: should be "nxp,lpc3220-clk"
5- reg:  should contain clock controller registers location and length
6- #clock-cells: must be 1, the cell holds id of a clock provided by the
7  clock controller
8- clocks: phandles of external oscillators, the list must contain one
9  32768 Hz oscillator and may have one optional high frequency oscillator
10- clock-names: list of external oscillator clock names, must contain
11  "xtal_32k" and may have optional "xtal"
