Reg:adding new module to x86_64 architecture in Ubuntu 16.04 LTS

Hi,

We are using Linux 4.15 on intel ATOM E3845 .we are working to develop a device driver. For ex: We are trying to integrate NFC pn54xx to intel x86_64 architecture. We need where to add hardware information of module in kernel.

Please let us know where we need to add the hardware information in Linux for x86_64 architecture. We are aware of modifying the device tree in ARM architecture but we are unsure of where we need to add the hardware information in x86_64 architecture. Please help.
