1Memory mapped Bosch CC770 and Intel AN82527 CAN controller2 3Note: The CC770 is a CAN controller from Bosch, which is 100%4compatible with the old AN82527 from Intel, but with "bugs" being fixed.5 6Required properties:7 8- compatible : should be "bosch,cc770" for the CC770 and "intc,82527"9 for the AN82527.10 11- reg : should specify the chip select, address offset and size required12 to map the registers of the controller. The size is usually 0x80.13 14- interrupts : property with a value describing the interrupt source15 (number and sensitivity) required for the controller.16 17Optional properties:18 19- bosch,external-clock-frequency : frequency of the external oscillator20 clock in Hz. Note that the internal clock frequency used by the21 controller is half of that value. If not specified, a default22 value of 16000000 (16 MHz) is used.23 24- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin.25 If not specified or if the specified value is 0, the CLKOUT pin26 will be disabled.27 28- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified,29 a reasonable value will be calculated.30 31- bosch,disconnect-rx0-input : see data sheet.32 33- bosch,disconnect-rx1-input : see data sheet.34 35- bosch,disconnect-tx1-output : see data sheet.36 37- bosch,polarity-dominant : see data sheet.38 39- bosch,divide-memory-clock : see data sheet.40 41- bosch,iso-low-speed-mux : see data sheet.42 43For further information, please have a look to the CC770 or AN82527.44 45Examples:46 47can@3,100 {48 compatible = "bosch,cc770";49 reg = <3 0x100 0x80>;50 interrupts = <2 0>;51 interrupt-parent = <&mpic>;52 bosch,external-clock-frequency = <16000000>;53};54
