Subject: [RFC PATCH v5 06/10] devicetree: bindings: Document first ROHM BD70528 bindings
Date: Mon, 4 Feb 2019 14:47:44 +0200 [thread overview]
Message-ID: <3b86b75b19e54c533ba6fe91f915981824dec3bd.1549283920.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1549283919.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 Iq 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 bits 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";
+};
