| fsl,mpc5200-mscan nodes |
| ----------------------- |
| In addition to the required compatible-, reg- and interrupt-properties, you can |
| also specify which clock source shall be used for the controller: |
| |
| - fsl,mscan-clock-source : a string describing the clock source. Valid values |
| are: "ip" for ip bus clock |
| "ref" for reference clock (XTAL) |
| "ref" is default in case this property is not |
| present. |
| |
| fsl,mpc5121-mscan nodes |
| ----------------------- |
| In addition to the required compatible-, reg- and interrupt-properties, you can |
| also specify which clock source and divider shall be used for the controller: |
| |
| - fsl,mscan-clock-source : a string describing the clock source. Valid values |
| are: "ip" for ip bus clock |
| "ref" for reference clock |
| "sys" for system clock |
| If this property is not present, an optimal CAN |
| clock source and frequency based on the system |
| clock will be selected. If this is not possible, |
| the reference clock will be used. |
| |
| - fsl,mscan-clock-divider: for the reference and system clock, an additional |
| clock divider can be specified. By default, a |
| value of 1 is used. |
| |
| Note that the MPC5121 Rev. 1 processor is not supported. |

| Examples: |
| can@1300 { |
| compatible = "fsl,mpc5121-mscan"; |
| interrupts = <12 0x8>; |
| interrupt-parent = <&ipic>; |
| reg = <0x1300 0x80>; |
| }; |
| |
| can@1380 { |
| compatible = "fsl,mpc5121-mscan"; |
| interrupts = <13 0x8>; |
| interrupt-parent = <&ipic>; |
| reg = <0x1380 0x80>; |
| fsl,mscan-clock-source = "ref"; |
| fsl,mscan-clock-divider = <3>; |
| }; |
