      regulator: of: Provide simplified DT parsing method · a0c7b164
      Mark Brown authored
      Currently regulator drivers which support DT all repeat very similar code
      to supply a list of known regulator identifiers to be matched with DT,
      convert that to platform data which is then matched up with the regulators
      as they are registered. This is both fiddly to get right and for devices
      which can use the standard helpers to provide their operations is the main
      source of code in the driver.
      
      Since this code is essentially identical for most drivers we can factor it
      out into the core, moving the identifiers in the match table into the
      regulator descriptors and also allowing drivers to pass in the name of the
      subnode to search. When a driver provides an of_match string for the
      regulator the core will attempt to use that to obtain init_data, allowing
      the driver to remove all explicit code for DT parsing and simply provide
      data instead.
      
      The current code leaks the phandles for the child nodes, this will be
      addressed incrementally and makes no practical difference for FDT anyway
      as the DT data structures are never freed.
