    Subject[PATCH AUTOSEL for 3.18 022/102] ARM: dts: imx6qdl-wandboard: Fix audio channel swap
    Date
    From: Fabio Estevam <fabio.estevam@nxp.com>

    [ Upstream commit 79935915300c5eb88a0e94fa9148a7505c14a02a ]

    When running a stress playback/stop loop test on a mx6wandboard channel
    swaps can be noticed randomly.

    Increasing the SGTL5000 LRCLK pad strength to its maximum value fixes
    the issue, so add the 'lrclk-strength' property to avoid the audio
    channel swaps.
