  There are two key functions provided by MT6397, MT6323 and other MediaTek
  PMICs: pwrkey and homekey.
  The key functions are defined as the subnode of the function node provided
  by the PMIC that is defined as a Multi-Function Device (MFD).

  For MediaTek MT6323/MT6397 PMIC bindings see
  Documentation/devicetree/bindings/mfd/mt6397.txt
