+description: |
+ 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
