In the MXC_SPI_RevA2_SetTSControl function in spi_reva2.c, I see the code:

case MXC_SPI_TSCONTROL_SW_APP:
    spi->ctrl0 &= ~(MXC_F_SPI_REVA_CTRL0_SS_ACTIVE);
    spi->ctrl0 &= ~(MXC_F_SPI_REVA_CTRL2_SS_POL);
    break;

The second spi->ctrl0 write should be spi->ctrl2, as the SS_POL field is in ctrl2 not ctrl0.
