1Memory mapped SJA1000 CAN controller from NXP (formerly Philips) 2 3Required properties: 4 5- compatible : should be "nxp,sja1000". 6 7- reg : should specify the chip select, address offset and size required 8 to map the registers of the SJA1000. The size is usually 0x80. 9 10- interrupts: property with a value describing the interrupt source 11 (number and sensitivity) required for the SJA1000. 12 13Optional properties: 14 15- nxp,external-clock-frequency : Frequency of the external oscillator 16 clock in Hz. Note that the internal clock frequency used by the 17 SJA1000 is half of that value. If not specified, a default value 18 of 16000000 (16 MHz) is used. 19 20- nxp,tx-output-mode : operation mode of the TX output control logic: 21 <0x0> : bi-phase output mode 22 <0x1> : normal output mode (default) 23 <0x2> : test output mode 24 <0x3> : clock output mode 25 26- nxp,tx-output-config : TX output pin configuration: 27 <0x01> : TX0 invert 28 <0x02> : TX0 pull-down (default) 29 <0x04> : TX0 pull-up 30 <0x06> : TX0 push-pull 31 <0x08> : TX1 invert 32 <0x10> : TX1 pull-down 33 <0x20> : TX1 pull-up 34 <0x30> : TX1 push-pull 35 36- nxp,clock-out-frequency : clock frequency in Hz on the CLKOUT pin. 37 If not specified or if the specified value is 0, the CLKOUT pin 38 will be disabled. 39 40- nxp,no-comparator-bypass : Allows to disable the CAN input comperator. 41 42For futher information, please have a look to the SJA1000 data sheet. 43 44Examples: 45 46can@3,100 { 47 compatible = "nxp,sja1000"; 48 reg = <3 0x100 0x80>; 49 interrupts = <2 0>; 50 interrupt-parent = <&mpic>; 51 nxp,external-clock-frequency = <16000000>; 52}; 53 54
