Subject: [PATCH v2 1/3] regulator: axp20x: add drivevbus support for axp803
Date: Fri, 8 Dec 2017 00:34:18 +0530 [thread overview]
Message-ID: <1512673460-7865-1-git-send-email-jagan@amarulasolutions.com> (raw)
Like axp221, axp223, axp813 the axp803 is also supporting external
regulator to drive the OTG VBus through N_VBUSEN PMIC pin.
Add support for it.
