Subject: [PATCH v2 07/17] dt_bindings: mfd: Add ROHM BD71815 PMIC
Date: Tue, 19 Jan 2021 09:21:23 +0200 [thread overview]
Message-ID: <5e58cc041572d8540b4f1fbeea7bde955d6b2ea6.1611037866.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1611037866.git.matti.vaittinen@fi.rohmeurope.com>
Document DT bindings for ROHM BD71815.
BD71815 is a single-chip power management IC mainly for battery-powered
portable devices. The IC integrates 5 bucks, 7 LDOs, a boost driver for
LED, a battery charger with a Coulomb counter, a real-time clock, a 32kHz
clock and two general-purpose outputs although only one is documented by
the data-sheet.

Changes since v1:
- fixed patch ordering to meet ref dependencies
- added missing blank lines
- clkout-mode changed from string to tristated (uint)
- added default for rsense resistor

+ BD71815AGW is a single-chip power management ICs for battery-powered
+ portable devices. It integrates 5 buck converters, 8 LDOs, a boost driver
+ for LED and a 500 mA single-cell linear charger. Also included is a Coulomb
+ counter, a real-time clock (RTC), and a 32.768 kHz clock gate and two GPOs.

+ description: |
+ The BD71815 has undocumented GPO at pin E5. Pin is marked as GND at the
+ data-sheet as it's location in the middle of GND pins makes it hard to
+ use on PCB. If your board has managed to use this pin you can enable the
+ second GPO by defining this property. Dont enable this if you are unsure
+ about how the E5 pin is connected on your board.
