+Aeroflex Gaisler GRCAN and GRHCAN CAN controllers.
+
+The GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
+library.
+
+Note: These properties are built from the AMBA plug&play in a Leon SPARC system
+(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
+sparc.
+
+Required properties:
+
+- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
+
+- reg : Address and length of the register set for the device
+
+- freq : Frequency of the external oscillator clock in Hz (the frequency of
+ the amba bus in the ordinary case)
+
+- interrupts : Interrupt number for this device
+
+Optional properties:
+
+- systemid : If not present or if the value of the least significant 16 bits
+ of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
+ a bug workaround is activated.
+
+For further information look in the documentation for the GLIB IP core library:
