Im getting this output from muxing:

MUX: setup AF6_3430_MCBSP3_DX (0xd800216c): 0x0004 ->
0x0000
MUX: setup AE6_3430_MCBSP3_DR (0xd800216e): 0x0004 ->
0x0000
MUX: setup AF5_3430_MCBSP3_CLKX (0xd8002170): 0x0004 ->
0x0000
MUX: setup AE5_3430_MCBSP3_FSX (0xd8002172): 0x0004 -> 0x0000

Is this correct?
