Hello All
we have T2081 custom board based on T2080RDB-PC,
i am confused in pin muxing and input output mapping,
as in case of IMX6UL we are specifically having pin muxing related header file present in U-boot and kernel,
i am trying to find the same for t2080RDB which i am not getting.
to configure the IO mapping as per the our custom board.
Any suggestion would be appreciated,kindly help to solve this issue.

From the provided wording it is not clear which exactly "pin muxing" is in question - please elaborate.
Consider that GPIO function can be assigned to several signals only in RCW and can't be altered by software means - refer to the QorIQ T2080 Reference Manual, Table 4-14. RCW Field Descriptions.
Hello ufedor,
we are using T2081 custom board based on T2080RDB-PC,
in which we have connected peripherals on few of the IO pins of T2081,
that pin mapping we have to assign in U-boot and kernel,
for which i am trying to find the respective header files which i am not getting,
How to configure the IO as per the our custom board.
Thanks in advance.
