Could you rebase this on top of i2c/for-next or v5.7-rcX? Because of
commit 90224e6468e1 ("i2c: drivers: Use generic definitions for bus
frequencies") which was added two days before your patch was sent out.
Otherwise mostly minor nits.

Maybe ternary operator here? Your choice.
And my code checkers complained:
CPPCHECK
drivers/i2c/busses/i2c-mt65xx.c:591:11: warning: Redundant assignment of 'sda_max' to itself. [selfAssignment]
sda_max = sda_max;
^
drivers/i2c/busses/i2c-mt65xx.c:597:11: warning: Redundant assignment of 'sda_min' to itself. [selfAssignment]
sda_min = sda_min;
Last question: You seem to be the one doing major updates to this
driver. Thanks for that! Are you maybe interested in becoming the
maintainer for this driver? I think there won't be much patches to
review and reports to handle but it will speed up processing for me.
All the best,
Wolfram
