AM3352: Inquery about CONTROL_MODULE Registers in Kernel

Takayuki Miyazaki

Part Number: AM3352

Hello team,

Regarding CONTROL_MODULE Registers, customer thinks those registers are configured in u-boot. Also, customer believe that those registers are configured in Linux Kernel. Customer is looking for this configuration file by "grep command", however, they were not able to find them. Could you elaborate it, please?

Customer would like to just clarify it.

Best regards, Miyazaki

This is a very broad question. The pinmux registers are part of the control module. Those are configured in the Linux dts file.

Adding on to Brad's answer:

on AM335x and AM437x, we expect customers to make changes to pinmux settings in the Linux devicetree. You would only need to make pinmux changes to U-boot if there is a need for the peripheral or gpio to be usable early on in u-boot.

Regards,

Nick
