1*4882a593SmuzhiyunMemory mapped Bosch CC770 and Intel AN82527 CAN controller 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunNote: The CC770 is a CAN controller from Bosch, which is 100% 4*4882a593Smuzhiyuncompatible with the old AN82527 from Intel, but with "bugs" being fixed. 5*4882a593Smuzhiyun 6*4882a593SmuzhiyunRequired properties: 7*4882a593Smuzhiyun 8*4882a593Smuzhiyun- compatible : should be "bosch,cc770" for the CC770 and "intc,82527" 9*4882a593Smuzhiyun for the AN82527. 10*4882a593Smuzhiyun 11*4882a593Smuzhiyun- reg : should specify the chip select, address offset and size required 12*4882a593Smuzhiyun to map the registers of the controller. The size is usually 0x80. 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun- interrupts : property with a value describing the interrupt source 15*4882a593Smuzhiyun (number and sensitivity) required for the controller. 16*4882a593Smuzhiyun 17*4882a593SmuzhiyunOptional properties: 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun- bosch,external-clock-frequency : frequency of the external oscillator 20*4882a593Smuzhiyun clock in Hz. Note that the internal clock frequency used by the 21*4882a593Smuzhiyun controller is half of that value. If not specified, a default 22*4882a593Smuzhiyun value of 16000000 (16 MHz) is used. 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin. 25*4882a593Smuzhiyun If not specified or if the specified value is 0, the CLKOUT pin 26*4882a593Smuzhiyun will be disabled. 27*4882a593Smuzhiyun 28*4882a593Smuzhiyun- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified, 29*4882a593Smuzhiyun a resonable value will be calculated. 30*4882a593Smuzhiyun 31*4882a593Smuzhiyun- bosch,disconnect-rx0-input : see data sheet. 32*4882a593Smuzhiyun 33*4882a593Smuzhiyun- bosch,disconnect-rx1-input : see data sheet. 34*4882a593Smuzhiyun 35*4882a593Smuzhiyun- bosch,disconnect-tx1-output : see data sheet. 36*4882a593Smuzhiyun 37*4882a593Smuzhiyun- bosch,polarity-dominant : see data sheet. 38*4882a593Smuzhiyun 39*4882a593Smuzhiyun- bosch,divide-memory-clock : see data sheet. 40*4882a593Smuzhiyun 41*4882a593Smuzhiyun- bosch,iso-low-speed-mux : see data sheet. 42*4882a593Smuzhiyun 43*4882a593SmuzhiyunFor further information, please have a look to the CC770 or AN82527. 44*4882a593Smuzhiyun 45*4882a593SmuzhiyunExamples: 46*4882a593Smuzhiyun 47*4882a593Smuzhiyuncan@3,100 { 48*4882a593Smuzhiyun compatible = "bosch,cc770"; 49*4882a593Smuzhiyun reg = <3 0x100 0x80>; 50*4882a593Smuzhiyun interrupts = <2 0>; 51*4882a593Smuzhiyun interrupt-parent = <&mpic>; 52*4882a593Smuzhiyun bosch,external-clock-frequency = <16000000>; 53*4882a593Smuzhiyun}; 54
