Hi All,

We are working on imx8mq processor-based custom design. We used Linux kernel 4.14 for development. We want to change the drive strength of USB 3.0 USB2 port.

The pins are following to needs to change drive strength.

USB2_DN
USB2_DP
USB2_TX_P
USB2_TX_N
USB2_RX_P
USB2_RX_N

Can you please share documents or file name to change this drive strength of USB2 port?

Thanks,
parth
