Well I just reverted the setting back to what it was on 2.6.36, before
the recent MX51 iomux reorganisation.
IOMUXC_UART2_IPP_UART_RXD_MUX_SELECT_INPUT register (0x09ec) shouldn't
be used to configure UART2_TXD PAD, otherwise you overwrite current
UART2_RXD PAD config.
Current pin configuration seems to act as a kind of Tx->Rx loopback, yes.

Without my patch, my board (not mainlined yet) can't receive anything on
UART2 (used as console).
