Hi,
I am new to Torizon core. I am trying to understand the Device tree customisation.
In device tree pinctrl along with Function ID we will define Configuration bits for Pad settings. In Pad setting bits the last 7 bits are for Pad Control Register and 31 bit is SION bit what are the remaining bits for and we are setting mux_mode through Function ID ,then what are remaining mux_reg, conf_reg, input_reg used for?

Is there any document regarding device tree function IDs and configuration bits definitions for all pins ?

Best wishes , Roshini.

Additionally you can check for below link if you wish to know more about how gpio device tree works.
