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