On Spreadtrum platform, we use one mfd driver [1] to populate the
SC27XX series PMICs including SC2731, SC2721, SC2720 and SC2730. So we
use sc27xx to be compatible with different PMICs' devices, otherwise
it will be difficult to define the mfd cell arrays in mfd driver. Do
you have any good suggestion? Thanks.
