      regulator: bd71828: Don't overwrite runtime voltages · 0f9f7c63
      Matti Vaittinen authored
      Some of the regulators on the BD71828 have common voltage setting for
      RUN/SUSPEND/IDLE/LPSR states. The enable control can be set for each
      state though.
      
      The driver allows setting the voltage values for these states via
      device-tree. As a side effect, setting the voltages for
      SUSPEND/IDLE/LPSR will also change the RUN level voltage which is not
      desired and can break the system.
      
      The comment in code reflects this behaviour, but it is likely to not
      make people any happier. The right thing to do is to allow setting the
      enable/disable state at SUSPEND/IDLE/LPSR via device-tree, but to
      disallow setting state specific voltages for those regulators.
      
      BUCK1 is a bit different. It only shares the SUSPEND and LPSR state
      voltages. The former behaviour of allowing to silently overwrite the
      SUSPEND state voltage by LPSR state voltage is also changed here so that
      the SUSPEND voltage is prioritized over LPSR voltage.
      
      Prevent setting PMIC state specific voltages for regulators which do not
      support it.

      regulator: new API for voltage reference supplies · 48b6faae
      Mark Brown authored
      Merge series from David Lechner <dlechner@baylibre.com>:
      
      In the IIO subsystem, we noticed a pattern in many drivers where we need
      to get, enable and get the voltage of a supply that provides a reference
      voltage. In these cases, we only need the voltage and not a handle to
      the regulator. Another common pattern is for chips to have an internal
      reference voltage that is used when an external reference is not
      available. There are also a few drivers outside of IIO that do the same.
      
      So we would like to propose a new regulator consumer API to handle these
      specific cases to avoid repeating the same boilerplate code in multiple
      drivers.
      
      As an example of how these functions are used, I have included a few
      patches to consumer drivers. But to avoid a giant patch bomb, I have
      omitted the iio/adc and iio/dac patches I have prepared from this
      series. I will send those separately but these will add 36 more users
      of devm_regulator_get_enable_read_voltage() in addition to the 6 here.
      In total, this will eliminate nearly 1000 lines of similar code and will
      simplify writing and reviewing new drivers in the future.
