[PATCH v4 0/2] add AD8460 DAC driver

[Mariel Tinaco]

Apply comments for adding support to AD8460 Waveform Generator DAC

changes in v4

ad8460:
  * Fixed spacing issues and tab format of includes.
  * Changed data type of spi_tx_buffer to __le16. Then used le16_to_cpu and
    cpu_to_le16 functions for bulk read and write access.
  * Changed print format in sysfs_emit for unsigned int.
  * Added comments on powerdown write function to describe logic.
  * Omitted "_shared" parameter in AD8460_CHAN_EXT_INFO. 
  * Applied further changes to channel definition (endianness = IIO_CPU and
    AD8460_CURRENT_CHAN output = 1).
  * Reformatted section that reads REFIO_1P2V voltage.
  * Fixed upper and lower limits for checking of REFIO_1P2V.
  * Removed comment for arming the device in probe function.
  * Created a section for IIO related includes.
  * Replaced mutex_init with devm_mutex_init.
  * Added and enabled the other supplies using regulator bulk enable
  * Handled devm_iio_channel_get error -EPROBE_DEFER by returning
    -EPROBE_DEFER

Bindings:
  * Removed description on clocks
  * Reverted GPIO pin name to shutdown-reset-GPIO
  * Added minimum, maximum and default for setting voltage, current and
    temperature
  * Added required supplies
  * Changed additionalProperties to unevaluatedProperties
