i.MX6QP RGMII_TXC timing trouble

[yoshida_kyohei]

Hi NXP Team.
I am working on i.MX6QP(MCIMX6QP6AVT1AA) custom board.
I am looking for a solution to add delay to the RGMII_TXC to meet timing specifications.
I read the datasheet(IMX6DQPAEC, Rev.3, 11/2018, P.87) and have two questions about the RGMII interface.

Question 1
Is there an alternative way to adding delays to RGMII_TXC other than long PCB trace?

Question 2
Are there any devices in the i.MX6QP series which have TXC_DLY bit?
MCIMX6QP6AVT1AA seems not to have the bit.

Hello,

 i.MX6 does not support internal delay (TXC_DLY).
Customers can try using PHYs, which supporting such feature.
