| 2 | |
| 3 | Required 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" |
| 12 | |
| 13 | Examples: |
| 14 | |
| 15 | /* System Control Block */ |
| 16 | scb { |
| 17 | compatible = "simple-bus"; |
| 18 | ranges = <0x0 0x040004000 0x00001000>; |
| 19 | #address-cells = <1>; |
| 20 | #size-cells = <1>; |
| 21 | |
| 22 | clk: clock-controller@0 { |
| 23 | compatible = "nxp,lpc3220-clk"; |
| 24 | reg = <0x00 0x114>; |
| 25 | #clock-cells = <1>; |
| 26 | |
| 27 | clocks = <&xtal_32k>, <&xtal>; |
| 28 | clock-names = "xtal_32k", "xtal"; |
