  regmap: Add regmap_noinc_read API (2018-08-09 11:00:15 +0100)

----------------------------------------------------------------
regmap: Support non-incrementing registers

Some devices have individual registers that don't autoincrement the
register address during bulk reads but instead repeatedly read the same
value, for example for monitoring GPIOs or ADCs.  Add support for these.
