Subject: [PATCH v10 4/9] devicetree: bindings: Document first ROHM BD70528 bindings
Date: Thu, 14 Feb 2019 15:08:09 +0200 [thread overview]
Message-ID: <90c3b820baf072a7cc3a21aa50c661774a045158.1550148989.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1550148989.git.matti.vaittinen@fi.rohmeurope.com>
Document bindings for regulators (3 bucks, 3 LDOs and 2 LED
drivers) and 4 GPIO pins which can be configured for I/O or
as interrupt sources withe configurable trigger levels.

+* ROHM BD70528 Power Management Integrated Circuit bindings
+
+BD70528MWV is an ultra-low quiescet current general purpose single-chip
+power management IC for battery-powered portable devices. The IC
+integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2
+LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz
+clock gate, high-accuracy VREF for use with an external ADC, flexible
+dual-input power path, 10 bit SAR ADC for battery temperature monitor and
+1S battery charger with scalable charge currents.
+
+Required properties:
+ - compatible : Should be "rohm,bd70528"
+ - reg : I2C slave address.
+ - interrupts : The interrupt line the device is connected to.
+ - interrupt-controller : To indicate BD70528 acts as an interrupt controller.
+ - #interrupt-cells : Should be 2. Usage is compliant to the 2 cells
+ variant of ../interrupt-controller/interrupts.txt
+ - gpio-controller : To indicate BD70528 acts as a GPIO controller.
+ - #gpio-cells : Should be 2. The first cell is the pin number and
+ the second cell is used to specify flags. See
+ ../gpio/gpio.txt for more information.
+ - #clock-cells : Should be 0.
+ - regulators: : List of child nodes that specify the regulators.
+ Please see ../regulator/rohm,bd70528-regulator.txt
+
+Optional properties:
+ - clock-output-names : Should contain name for output clock.
+
+Example:
+/* external oscillator */
+osc: oscillator {
+ compatible = "fixed-clock";
+ #clock-cells = <1>;
+ clock-frequency = <32768>;
+ clock-output-names = "osc";
+};
