Where is GPIO pin MUX defined for Sitara AM3359 SK board?

Other Parts Discussed in Thread: AM3359

Hi,

I find an interesting link on GPIO pin setting for DM8168:

https://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/248588

I want to do similar thing to Sitara AM3359 SK board. My computer is installed SDK for processor 1.00.00.03. I don't see the file content in board-ti8168evm.c in the original post, though the file board-ti8168evm.c is in the same folder. This is perhaps because there are some big changes to this SDK. Could anybody tell me where is the equivalent file for Sitara AM3359 SK for the pin MUX redefinition?

Thanks,

    Hi Jeff,
    It is latest SDK which has latest linux kernel version that has DTS support.
    You have to check the following location for PINMUX stuff and configuring the board support stuff from the following location.

    arch/arm/boot/dts/am335x-evm.dts
    I've no worked much on AM335x DTS support, so please check that location similar to that files that has AM335x name.
