Hi Xu

one can check sect.2.1.5.6 IOMUX Control Through GPIO Module attached Linux Manual and

sect.Chapter 8 Configuring IOMUX Porting Guide from nxp software documentation link below

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6ser...

For i.MX8 series use SCFW documentation in SCFW Porting Kit

Best regards
igor
