| description: | |
| MT6397/MT6323 is a power management system chip. |
| Please see the sub-modules below for supported features. |
| |
| MT6397/MT6323 is a multifunction device with the following sub modules: |
| - Regulators |
| - RTC |
| - ADC |
| - Audio codec |
| - GPIO |
| - Clock |
| - LED |
| - Keys |
| - Power controller |
| |
| It is interfaced to host controller using SPI interface by a proprietary hardware |
| called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap. |
| See the following for pwrap node definitions: |

| MT6323 LED controller is subfunction provided by MT6323 PMIC, so the LED |

| using shared bus called PMIC wrapper for each subfunction to access remote |
| MT6323 PMIC hardware. |
| |
| Each led is represented as a child node of the mediatek,mt6323-led that |
| describes the initial behavior for each LED physically and currently only four |
| LED child nodes can be supported. |
