[PATCH v3 1/8] mfd: arizona: Split INx_MODE into two fields

Richard Fitzgerald
2015-05-01T15:16:19Z

Later arizona silicon has the single/differential selector
in a different register, and IN1_MODE only selects between
analogue or digital. Prepare for this by splitting the
INx_MODE definition into two fields.
