1CAN Device Tree Bindings 2------------------------ 3 4(c) 2006-2009 Secret Lab Technologies Ltd 5Grant Likely <grant.likely@secretlab.ca> 6 7fsl,mpc5200-mscan nodes 8----------------------- 9In addition to the required compatible-, reg- and interrupt-properties, you can 10also specify which clock source shall be used for the controller: 11 12- fsl,mscan-clock-source : a string describing the clock source. Valid values 13 are: "ip" for ip bus clock 14 "ref" for reference clock (XTAL) 15 "ref" is default in case this property is not 16 present. 17 18fsl,mpc5121-mscan nodes 19----------------------- 20In addition to the required compatible-, reg- and interrupt-properties, you can 21also specify which clock source and divider shall be used for the controller: 22 23- fsl,mscan-clock-source : a string describing the clock source. Valid values 24 are: "ip" for ip bus clock 25 "ref" for reference clock 26 "sys" for system clock 27 If this property is not present, an optimal CAN 28 clock source and frequency based on the system 29 clock will be selected. If this is not possible, 30 the reference clock will be used. 31 32- fsl,mscan-clock-divider: for the reference and system clock, an additional 33 clock divider can be specified. By default, a 34 value of 1 is used. 35 36Note that the MPC5121 Rev. 1 processor is not supported. 37 38Examples: 39 can@1300 { 40 compatible = "fsl,mpc5121-mscan"; 41 interrupts = <12 0x8>; 42 interrupt-parent = <&ipic>; 43 reg = <0x1300 0x80>; 44 }; 45 46 can@1380 { 47 compatible = "fsl,mpc5121-mscan"; 48 interrupts = <13 0x8>; 49 interrupt-parent = <&ipic>; 50 reg = <0x1380 0x80>; 51 fsl,mscan-clock-source = "ref"; 52 fsl,mscan-clock-divider = <3>; 53 };
