Subject: [PATCH RESEND v13 4/8] dt-bindings: mfd: Document first ROHM BD70528 bindings
Date: Thu, 25 Apr 2019 14:15:35 +0300
Message-ID: <resend.9208a23a40127df32d3efc6e0ac02d9fcd49d80e.1554371464.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover2.1554371464.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 quiescent 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";
