Memory mapped Bosch CC770 and Intel AN82527 CAN controller Note: The CC770 is a CAN controller from Bosch, which is 100% compatible with the old AN82527 from Intel, but with "bugs" being fixed. Required properties: - compatible : should be "bosch,cc770" for the CC770 and "intc,82527" for the AN82527. - reg : should specify the chip select, address offset and size required to map the registers of the controller. The size is usually 0x80. - interrupts : property with a value describing the interrupt source (number and sensitivity) required for the controller. Optional properties: - bosch,external-clock-frequency : frequency of the external oscillator clock in Hz. Note that the internal clock frequency used by the controller is half of that value. If not specified, a default value of 16000000 (16 MHz) is used. - bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin. If not specified or if the specified value is 0, the CLKOUT pin will be disabled. - bosch,slew-rate : slew rate of the CLKOUT signal. If not specified, a reasonable value will be calculated. - bosch,disconnect-rx0-input : see data sheet. - bosch,disconnect-rx1-input : see data sheet. - bosch,disconnect-tx1-output : see data sheet. - bosch,polarity-dominant : see data sheet. - bosch,divide-memory-clock : see data sheet. - bosch,iso-low-speed-mux : see data sheet. For further information, please have a look to the CC770 or AN82527. Examples: can@3,100 { compatible = "bosch,cc770"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; bosch,external-clock-frequency = <16000000>; };
