Subject: [PATCH v6 03/15] dt-bindings: mfd: Document ROHM BD71828 bindings
Date: Wed, 11 Dec 2019 11:37:59 +0200 [thread overview]
Message-ID: <c910b9a057e76044291a4d669530ccf19225675f.1576054779.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1576054779.git.matti.vaittinen@fi.rohmeurope.com>
ROHM BD71828 Power management IC integrates 7 buck converters, 7 LDOs,
a real-time clock (RTC), 3 GPO/regulator control pins, HALL input
and a 32.768 kHz clock gate.
Document the dt bindings drivers are using.

+description: |
+ BD71828GW is a single-chip power management IC for battery-powered portable
+ devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
+ single-cell linear charger. Also included is a Coulomb counter, a real-time
+ clock (RTC), and a 32.768 kHz clock gate.
