Subject: [PATCH 0/5] staging: ad9832: driver cleanup

This series cleans up the ad9832 driver with the goal of (eventually)
graduating it from staging. The main change is converting custom sysfs
attributes to IIO channel interface and adding sysfs documentation.

Changes since RFC:
  - Split unrelated changes into separate patches: whitespace cleanup,
    guard() conversion and dev_err_probe() (Jonathan)
  - Changed channel type from IIO_ALTVOLTAGE to IIO_ALTCURRENT since
    this is a current source DAC (Jonathan)
  - Kept single channel with ext_info for frequencyN/phaseN attributes
    rather than multiple indexed channels, as the device has only one
    output (Jonathan)
  - Phase attributes now accept radians directly instead of raw register
    values, driver performs the conversion internally (Jonathan)
  - Added read callbacks for frequency and phase attributes
  - Added TODO comment for pincontrol_en noting it should become a DT
    property during graduation (Jonathan)
  - Added ABI documentation for new sysfs attributes
