There are 2 parameters for the description of pins in the device tree:
·MX8MP_IOMUXC_GPIO1_IO01__PWM1_OUT describes the pin multiplexing relationship
·0x116 describes the electrical properties of the pin
The DEBIX pin multiplexing relationships can be found in imx8mp-pinfunc.h.
The electrical attribute parameters of the DEBIX pin are set as follows:
1.Open the official configuration tool Config Tools for i.MX v13, select File -> New
2.Create a new configuration, click Next
