Subject: ARM: dts: imx6ul-txul: specify ethernet phy reset post-delay
X-Git-Tag: KARO-TX6-2017-10-26~3^2~4

ARM: dts: imx6ul-txul: specify ethernet phy reset post-delay

Under certain circumstances the ethernet PHY cannot be detected on
Ka-Ro electronics TXUL modules. Using a phy-reset-post-delay of > 5ms
alleviates this problem. Specify a value of 10ms to be on the safe side.
