How to configure flexcan mailbox ?

Contributor I

I am trying to configure the mailbox settings in flexcan on a i.MX 6Ultra Lite SoC. I am new to this and i am not sure from where to start.
I came to understand that mailbox can be configured from the kernel layer and not necessarily from the application layer.  I am using a kernel version 4.9, but i am not sure what changes to flexcan.c can help me configure the mailboxes. Any sample code or reference to some documents will be appreciated. 
Thanks in advance.

Sorry, we don't have example.

For the details of flexcan, you can read the Chapter 24 in i.MX6ULRM. You can download the reference manual from here : i.MX 6UltraLite Applications Processor | Single Arm® Cortex®-A7 @ 696 MHz | NXP 

For the driver details, please read the attached Linux reference manual.
