Subject: [PATCH v6 1/8] dt-bindings: mfd: document stpmic1
Date: Tue, 27 Nov 2018 16:52:14 +0000 [thread overview]
Message-ID: <1543337529-22301-2-git-send-email-p.paillet@st.com> (raw)
In-Reply-To: <1543337529-22301-1-git-send-email-p.paillet@st.com>
STPMIC1 is a PMIC from STMicroelectronics. The STPMIC1 integrates 10
regulators, 3 power switches, a watchdog and an input for a power on key.

+* STMicroelectronics STPMIC1 Power Management IC
+
+Required properties:
+- compatible: : "st,stpmic1"
+- reg: : The I2C slave address for the STPMIC1 chip.
+- interrupts: : The interrupt line the device is connected to.
+- #interrupt-cells: : Should be 1.
+- interrupt-controller: : Marks the device node as an interrupt controller.
+ Interrupt numbers are defined at
+ dt-bindings/mfd/st,stpmic1.h.
+
+STPMIC1 consists in a varied group of sub-devices.
+Each sub-device binding is be described in own documentation file.
+
+Device Description
+------ ------------
+st,stpmic1-onkey : Power on key, see ../input/st,stpmic1-onkey.txt
+st,stpmic1-regulators : Regulators, see ../regulator/st,stpmic1-regulator.txt
+st,stpmic1-wdt : Watchdog, see ../watchdog/st,stpmic1-wdt.txt
+
+Example:
+
+#include <dt-bindings/mfd/st,stpmic1.h>
+
+pmic: pmic@33 {
+ compatible = "st,stpmic1";
+ reg = <0x33>;
+ interrupt-parent = <&gpioa>;
+ interrupts = <0 2>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+
+ onkey {
+ compatible = "st,stpmic1-onkey";
+ interrupts = <IT_PONKEY_F 0>,<IT_PONKEY_R 1>;
+ interrupt-names = "onkey-falling", "onkey-rising";
+ power-off-time-sec = <10>;
+ };
+
+ watchdog {
+ compatible = "st,stpmic1-wdt";
+ };
+
+ regulators {
+ compatible = "st,stpmic1-regulators";
+
+ vdd_core: buck1 {
+ regulator-name = "vdd_core";
+ regulator-boot-on;
+ regulator-min-microvolt = <700000>;
