description: |
|
|
Add support for SCHGM_FLASH module under charger.
|
|
SCHGM_FLASH module handles flash failure, de-rating and
|
|
allows configuration for different flash features.

Specifies flash hardware headroom management policy.
|

|
0 - Fixed mode, constant 5V at flash input.
|
|
1 - Adaptive mode allows charger output voltage to be

has SCHGM_FLASH peripheral.
