1*4882a593SmuzhiyunAeroflex Gaisler GRCAN and GRHCAN CAN controllers.
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
4*4882a593Smuzhiyunlibrary.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunNote: These properties are built from the AMBA plug&play in a Leon SPARC system
7*4882a593Smuzhiyun(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
8*4882a593Smuzhiyunsparc.
9*4882a593Smuzhiyun
10*4882a593SmuzhiyunRequired properties:
11*4882a593Smuzhiyun
12*4882a593Smuzhiyun- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
13*4882a593Smuzhiyun
14*4882a593Smuzhiyun- reg : Address and length of the register set for the device
15*4882a593Smuzhiyun
16*4882a593Smuzhiyun- freq : Frequency of the external oscillator clock in Hz (the frequency of
17*4882a593Smuzhiyun	the amba bus in the ordinary case)
18*4882a593Smuzhiyun
19*4882a593Smuzhiyun- interrupts : Interrupt number for this device
20*4882a593Smuzhiyun
21*4882a593SmuzhiyunOptional properties:
22*4882a593Smuzhiyun
23*4882a593Smuzhiyun- systemid : If not present or if the value of the least significant 16 bits
24*4882a593Smuzhiyun	of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
25*4882a593Smuzhiyun	a bug workaround is activated.
