+
+Required properties:
+- compatible		: Should be "bosch,c_can" for C_CAN controllers and
+			  "bosch,d_can" for D_CAN controllers.
+			  Can be "ti,dra7-d_can", "ti,am3352-d_can" or
+			  "ti,am4372-d_can".
+- reg			: physical base address and size of the C_CAN/D_CAN

+(the ordinary environment for GRCAN and GRHCAN). There are no dts files for

+
+- reg : Address and length of the register set for the device

+- 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.

+Bosch MCAN controller Device Tree Bindings
+-------------------------------------------------
+
+Required properties:
+- compatible		: Should be "bosch,m_can" for M_CAN controllers
+- reg			: physical base address and size of the M_CAN
+			  registers map and Message RAM
+- reg-names		: Should be "m_can" and "message_ram"
+- interrupts		: Should be the interrupt number of M_CAN interrupt
+			  line 0 and line 1, could be same if sharing
+			  the same interrupt.
+- interrupt-names	: Should contain "int0" and "int1"
+- clocks		: Clocks used by controller, should be host clock
+			  and CAN clock.
+- clock-names		: Should contain "hclk" and "cclk"
+- pinctrl-<n>		: Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
+- pinctrl-names 	: Names corresponding to the numbered pinctrl states
+- bosch,mram-cfg	: Message RAM configuration data.
+			  Multiple M_CAN instances can share the same Message
+			  RAM and each element(e.g Rx FIFO or Tx Buffer and etc)
+			  number in Message RAM is also configurable,
+			  so this property is telling driver how the shared or
+			  private Message RAM are used by this M_CAN controller.
+
+			  The format should be as follows:
+			  <offset sidf_elems xidf_elems rxf0_elems rxf1_elems
+			   rxb_elems txe_elems txb_elems>
+			  The 'offset' is an address offset of the Message RAM
+			  where the following elements start from. This is
+			  usually set to 0x0 if you're using a private Message
+			  RAM. The remain cells are used to specify how many
+			  elements are used for each FIFO/Buffer.
+
+			  M_CAN includes the following elements according to user manual:
+			  11-bit Filter	0-128 elements / 0-128 words
+			  29-bit Filter	0-64 elements / 0-128 words
+			  Rx FIFO 0	0-64 elements / 0-1152 words
+			  Rx FIFO 1	0-64 elements / 0-1152 words
+			  Rx Buffers	0-64 elements / 0-1152 words
+			  Tx Event FIFO	0-32 elements / 0-64 words
+			  Tx Buffers	0-32 elements / 0-576 words
+
+			  Please refer to 2.4.1 Message RAM Configuration in
+			  Bosch M_CAN user manual for details.
+
+Example:
+SoC dtsi:
+m_can1: can@020e8000 {

+
+fsl,mpc5200-mscan nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source shall be used for the controller:
+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+			   are:	"ip" for ip bus clock
+				 "ref" for reference clock (XTAL)

+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can

+				"sys" for system clock
+			   If this property is not present, an optimal CAN
+			   clock source and frequency based on the system
+			   clock will be selected. If this is not possible,
+			   the reference clock will be used.
+
+- fsl,mscan-clock-divider: for the reference and system clock, an additional
