On some firmware variants, the size of the info block exceeds what can
be read in a single transfer.

Is this limitation of the mXT controller or maybe it is issue with
implementation of the particular i2c adapter and should be dealt with
there?

This patch was authored by Nick,
but I assume it is trying to address issue due to I2C adapter limitation
which following patch in this series is already doing
"Input: atmel_mxt_ts: Limit the max bytes transferred in an i2c transaction"

I will extend patch "Input: atmel_mxt_ts: Limit the max bytes transferred in an i2c transaction"
to also cover this case.

Thanks,
Jiada

Thanks.
