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. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> --- arch/arm/boot/dts/imx6qdl-tx6.dtsi | 1 + 1 file changed, 1 insertion(+)
