29

30
+	  converting bitfields between a CPU-usable representation and a
31
+	  memory representation that can have any combination of these quirks:
32
+	    - Is little endian (bytes are reversed within a 32-bit group)
33
+	    - The least-significant 32-bit word comes first (within a 64-bit
34
+	      group)
35
+	    - The most significant bit of a byte is at its right (bit 0 of a
36
+	      register description is numerically 2^7).
37
+	  Drivers may use these helpers to match the bit indices as described
38
+	  in the data sheets of the peripherals they are in control of.
39
+
40
+	  When in doubt, say N.
