    Subject[PATCH 06/12] ARM: dts: imx6-tx6: specify ethernet phy reset post-delay
    Date
    Under certain circumstances the ethernet PHY cannot be detected on
    Ka-Ro electronics TX6 modules. Using a phy-reset-post-delay of at least
    2ms alleviates this problem. Define it to 10ms to be on the safe side.
