This is a set of patches to add support to the JZ4760(B) socs found in numerous gaming handhelds and some
mp3 players to the ingenic-sadc driver.

Changelog for this v4:

Fix patch 4/5 that was missing the .compatible string for the jz4760b.

Christophe Branchereau (5):
  iio/adc: ingenic: rename has_aux2 to has_aux_md
  dt-bindings: iio/adc: add an INGENIC_ADC_AUX0 entry
  iio/adc: ingenic: add JZ4760 support to the sadc driver
  iio/adc: ingenic: add JZ4760B support to the sadc driver
  dt-bindings: iio/adc: ingenic: add the JZ4760(B) socs to the sadc

The jz4760(b) socs have 3 aux channels.

The purpose of has_aux2 is to set the MD bits used to select
the AUX channel to be sampled, not to describe the hardware.

Rename it to a more appropriate name.

The JZ4760(B) socs have 3 AUX inputs, add an entry to prepare including the one named AUX in the sadc driver.
Leaving the rest untouched as it's ABI.

The jz4760 sadc is very similar to the jz4770 one, but has a VREF of 2.5V
and 3 aux channels.

modify ingenic_adc_read_chan_info_raw() needs a change to account for it.

The JZ4760B variant differs slightly from the JZ4760: it has a bit called VBAT_SEL in the CFG register.

In order to correctly sample the battery voltage on existing handhelds using this SOC, the bit must be cleared.

We leave the possibility to set the bit, by using the "ingenic,use-internal-divider" in the devicetree.

Add both the jz4760 and jz4760b, plus a property to use the internal
divider on the b variant and document it.
