| 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. |
