| 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. | |
