ath10k otp.bin board.bin firmware.bin art.bin?

[孙建希]

I have solved this problem.
I am using LEDE Linux version 4.4.61. Device is a WF-96A  from CIG shanghai.

WF-96A write calibration data in spi flash. I have success read it to
`ath10k/cal-pci-0000:00:00.0.bin`. LEDE default use firmware-5.bin for
QCA988X. But `ath10k/cal-pci-0000:00:00.0.bin` can only work with
firmware-4.bin.

What is the full name of otp? How does otp work?
Should we pay attention to the version of calibration and firmware ?
