+- pinctrl-names 	: Names corresponding to the numbered pinctrl states

+			  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
