Could it be the i2c input clock definition in drivers/mfd/intel-lpss-pci.c
is also wrong for Apollo Lake (N3450) ? There are lots of people having
various issues with i2c attached touchpads on Apollo Lake devices, this bug:

Is sort of a collection bug for these. Various models laptops, lots of
reporters. Note not sure thie is an i2c-designware issue, but it would
be good to double check the input clock on Apollo Lake.
Does i2c_designware_core.dyndbg=+p and i2c-hid.debug=1 command line arguments give any useful debug information from those machines?
A first dmesg with these flags has been provided:
