Memory mapped SJA1000 CAN controller from NXP (formerly Philips) Required properties: - compatible : should be one of "nxp,sja1000", "technologic,sja1000". - reg : should specify the chip select, address offset and size required to map the registers of the SJA1000. The size is usually 0x80. - interrupts: property with a value describing the interrupt source (number and sensitivity) required for the SJA1000. Optional properties: - reg-io-width : Specify the size (in bytes) of the IO accesses that should be performed on the device. Valid value is 1, 2 or 4. This property is ignored for technologic version. Default to 1 (8 bits). - nxp,external-clock-frequency : Frequency of the external oscillator clock in Hz. Note that the internal clock frequency used by the SJA1000 is half of that value. If not specified, a default value of 16000000 (16 MHz) is used. - nxp,tx-output-mode : operation mode of the TX output control logic: <0x0> : bi-phase output mode <0x1> : normal output mode (default) <0x2> : test output mode <0x3> : clock output mode - nxp,tx-output-config : TX output pin configuration: <0x01> : TX0 invert <0x02> : TX0 pull-down (default) <0x04> : TX0 pull-up <0x06> : TX0 push-pull <0x08> : TX1 invert <0x10> : TX1 pull-down <0x20> : TX1 pull-up <0x30> : TX1 push-pull - nxp,clock-out-frequency : clock frequency in Hz on the CLKOUT pin. If not specified or if the specified value is 0, the CLKOUT pin will be disabled. - nxp,no-comparator-bypass : Allows to disable the CAN input comparator. For further information, please have a look to the SJA1000 data sheet. Examples: can@3,100 { compatible = "nxp,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; nxp,external-clock-frequency = <16000000>; };
