    Subject[PATCH v3 05/24] ARM: dts: imx6qdl-sabrelite: remove erratum ERR006687 workaround
    Date
    There is a pin conflict with GPIO_6. This pin functions as a power
    input pin to the OV5642 camera sensor, but ENET uses it as the h/w
    workaround for erratum ERR006687, to wake-up the ARM cores on normal
    RX and TX packet done events. So we need to remove the h/w workaround
    to support the OV5642. The result is that the CPUidle driver will no
    longer allow entering the deep idle states on the sabrelite.

    This is a partial revert of

    commit 6261c4c8f13e ("ARM: dts: imx6qdl-sabrelite: use GPIO_6 for FEC
    interrupt.")
    commit a28eeb43ee57 ("ARM: dts: imx6: tag boards that have the HW workaround
    for ERR006687")
