| 5 | This is a configurable clock fed from a 24 MHz chrystal, |
| 6 | used for generating e.g. video clocks. It is located on the |
| 7 | core module and there is only one of these. |
| 8 | |
| 9 | This clock node *must* be a subnode of the core module, since |
| 10 | it obtains the base address for it's address range from its |
| 11 | parent node. |

| 14 | Required properties: |
Rob Herring | f27e861 | 2014-03-29 13:36:18 -0500 | [diff] [blame] | 15 | - compatible: must be "arm,integrator-cm-auxosc" or "arm,versatile-cm-auxosc" |
Linus Walleij | 09c978b | 2014-01-10 15:57:27 +0100 | [diff] [blame] | 16 | - #clock-cells: must be <0> |
| 17 | |
| 18 | Optional properties: |
| 19 | - clocks: parent clock(s) |
| 20 | |
| 21 | Example: |
| 22 | |
| 23 | core-module@10000000 { |
| 24 | xtal24mhz: xtal24mhz@24M { |
| 25 | #clock-cells = <0>; |
| 26 | compatible = "fixed-clock"; |
| 27 | clock-frequency = <24000000>; |
| 28 | }; |
| 29 | auxosc: cm_aux_osc@25M { |
| 30 | #clock-cells = <0>; |
| 31 | compatible = "arm,integrator-cm-auxosc"; |
| 32 | clocks = <&xtal24mhz>; |
| 33 | }; |
| 34 | }; |
