Yep and just to verify I tried it:

I tried setting it as 0x02 and it still works! So I get the exact same 
behavior whether it is:

pinctrl-single,pins = <

                    0x198 0x20 /* mcasp0_axr0, INPUT | MODE0 */

                    0x1a8 0x20 /* mcasp0_axr1, INPUT | MODE0 */

                    0x19c 0x02 /* mcasp0_axr2, OUTPUT | MODE2 */

                    0x1a4 0x02 /* mcasp0_axr3, OUTPUT | MODE2 */


Or


pinctrl-single,pins = <

                    0x198 0x20 /* mcasp0_axr0, INPUT | MODE0 */

                    0x1a8 0x20 /* mcasp0_axr1, INPUT | MODE0 */

                    0x19c 0x22 /* mcasp0_axr2, INPUT | MODE2 */

                    0x1a4 0x22 /* mcasp0_axr3, INPUT | MODE2 */


As long as the serializer is correct...


Thanks for all your help and explanations John!!!


We are going to try 8 channels TDM next using 1 pin... not sure if you 
tried anything like this yet...
