With regmap->reg_base and regmap->reg_downshift, the actual register

reg_base and shifted, which will affect alignment.

Check for alignment on the real register address.

It is not at all clear to me that the combination of stride and
downshift particularly makes sense, and especially not that the
stride should be applied after downshifting rather than to what
the user is passing in.
