^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) There are two key functions provided by MT6397/MT6323 PMIC, pwrkey
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) and homekey. The key functions are defined as the subnode of the function
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) node provided by MT6397/MT6323 PMIC that is being defined as one kind
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) of Muti-Function Device (MFD)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)
