[PATCH v2 0/5] iio: dac: ad5758: fix the 4 mA to 20 mA current range

[Arka Mondal <arka@arkamondal.net>]

These are patches 4 and 5 of the v1 series, with the deprecated
<4 24000> value dropped as Rob Herring <robh@kernel.org> and
Jonathan Cameron <jic23@kernel.org> asked. Patches 1 to 3 are already
applied on togreg and are not resent.

The binding and the driver give the 4 mA to 20 mA range as <4 24000>,
which is 4 uA to 24 mA. The data sheet (Rev. B, Table 32) and the
original text binding say range code 1010 is 4 mA to 20 mA.

Changes since v1:
- binding: replace <4 24000> with <4000 20000>, instead of adding the
  correct pair and marking the old one deprecated.
- driver: drop the mapping from <4 24000> to the corrected range.

A device tree that still has <4 24000> now fails the binding check, and
probe stops with "range invalid".

Compile tested only; no relevant hardware available. The binding was
checked with make dt_binding_check and with test device trees:
<4000 20000> is accepted, <4 24000> is now rejected.
