[PATCH v2 1/3] regulator: tps65917/palmas: Add bypass ops for LDOs with bypass capability

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



set/get_bypass ops were missing for ldo1/ldo2 on tps65917 and
ldo9 on palmas/tps659038 which support bypass mode.
Adding the bypass ops helps consumers configure these ldos in
bypass mode or remove bypass mode if need be.

Changes in v2:

 * Added palmas/tps659038 ldo9 bypass ops.
