Hi, Dmitry,
Thanks for your comments.

This driver is intend to support two controllers, WDT8753 & WDT8756.
The chip_id and the the firmware are different for them, so we have to check if
The firmware is suitable for this controller.

The MISR is a checksum function which the full name is "Multiple Input
Signature Register".
I checked the kernel library and not found any algorithm like this.
You mean I have to submit the checksum function into kernel/lib ?

Yes, it always send all 10 contacts data.
