This patch removes the in_voltage-voltage_scale_available and
in_voltage_scale_available attributes. These are replaced with available
attributes added in info_mask_shared_by_type_available.
With this modification the iio core will be responsible with naming the
attributes thus removing the checkpatch warning related to
in_voltage-voltage_scale_available naming.

Change device attributes' names to match ABI documentation. Names were
chosen such that they tend to be similar to existing ABI so it should
be easier to standardize them when necessary.

Move ad7780 ADC driver out of staging and into the mainline.
The ad7780 is a sigma-delta analog to digital converter. This driver provides
reading voltage values and status bits from both the ad778x and ad717x series.
Its interface also allows writing on the FILTER and GAIN GPIO pins on the
ad778x.

The lsb calculation is not masking the correct bits from the user input.
Subtract 1 from (1 << offset) to correctly set up the mask to be applied
to user input.
The lsb register stores its value starting at the bit 7 position.
adt7316_store_DAC() currently assumes the value is at the other end of the
register. Shift the lsb value before storing it in a new variable lsb_reg,
and write this variable to the lsb register.

The adt7316/7 and adt7516/7 have the option to output voltage proportional
to temperature on dac a and/or dac b. The default dac resolution in this
mode is 8 bits with the dac high resolution option enabling 10 bits. None
of these settings affect dacs c and d. Remove the "1 (12 bits)" output from
the show function since that is not an option for this mode. Return
"1 (10 bits)" if the device is one of the above mentioned chips and the dac
high resolution mode is enabled.
In the store function, the driver currently allows the user to write to the
ADT7316_DA_HIGH_RESOLUTION bit regardless of the device in use. Add a check
to return an error in the case of an adt7318 or adt7519. Remove the else
statement that clears the ADT7316_DA_HIGH_RESOLUTION bit. Instead, clear it
before conditionally enabling it, depending on user input. This matches the
typical pattern in the driver when an attribute is a boolean.

The value of dac_bits is used in adt7316_show_DAC() and adt7316_store_DAC(),
and it should be either 8, 10, or 12 bits depending on the device in use. The
driver currently only assigns a value to dac_bits in
adt7316_store_da_high_resolution(). The purpose of the dac high resolution
option is not to change dac resolution for normal operation. Instead, it
is specific to an optional feature where one or two of the four dacs can
be set to output voltage proportional to temperature. If the user chooses
to set dac a and/or dac b to output voltage proportional to temperature,
the da_high_resolution attribute can optionally be enabled to use 10 bit
resolution rather than the default 8 bits. This is only available on the
10 and 12 bit dac devices. If the user attempts to read or write dacs a
or b under these settings, the driver's current behaviour is to return an
error. Dacs c and d continue to operate normally under these conditions.
With the above in mind, remove the dac_bits assignments from this function
since the value of dac_bits as used in the driver is not dependent on this
dac high resolution option.
Since the dac_bits assignments discussed above are currently the only ones
in this driver, the default value of dac_bits is 0. This results in incorrect
calculations when the dacs are read or written in adt7316_show_DAC() and
adt7316_store_DAC(). To correct this, assign a value to dac_bits in
adt7316_probe() to ensure correct operation as soon as the device is
registered and available to userspace.
