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. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> --- arch/arm/boot/dts/imx6ul-tx6ul.dtsi | 1 + 1 file changed, 1 insertion(+)
