Question about mt7981 precal size

[Zhi-Jun You]

Hi,

I am trying to convert my device to read EEPROM and precal through
NVMEM but encountered a problem with precal size.

Based on documentation and 19a954e, set the precal size to 54K + 16 +
102K = 159760 but I got a warning saying it failed to load precal and
the size is 200720. Added some debug line for the precal sizes I got:

mt798x-wmac 18000000.wifi: group size=96272
mt798x-wmac 18000000.wifi: dpd size=104448
mt798x-wmac 18000000.wifi: precal size=200720

mt7981 is using 2.4G + 6G cal group size but why? Then I took a look
at the vendor driver and it's using 2.4G + 5G + 6G cal group size
which looks even weirder.

So which one is the correct size? I assume the correct size should be
the same as the vendor driver but I might be wrong.

Best regards,
Zhi-Jun
