Subject: [PATCH] regulator: axp20x: Turn N_VBUSEN to input on
|
|
x-powers,sense-vbus-en
|
|
|
|
When x-powers,sense-vbus-en is present on the PMIC DT node, force
|
|
the N_VBUSEN to be an input. This is necessary on boards that
|
|
have N_VBUSEN connected to VBUS enabling switch to make PMIC
|
|
not charge when the board is generating VBUS voltage itself.
|
|
