-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 resonable 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>;
-};
