+ The Azoteq IQS620A, IQS621, IQS622, IQS624 and IQS625 multi-function sensors
+ feature a variety of self-capacitive, mutual-inductive and Hall-effect sens-
+ ing capabilities that can facilitate a variety of contactless key and switch
+ applications.
+
+ These functions are collectively represented by a "keys" child node from the
+ parent MFD driver. See Documentation/devicetree/bindings/mfd/iqs62x.yaml for
+ further details and examples. Sensor hardware configuration (self-capacitive
+ vs. mutual-inductive, etc.) is selected based on the device's firmware.

-* ROHM BD71837 and BD71847 Power Management Integrated Circuit bindings
-
-BD71837MWV and BD71847MWV are programmable Power Management ICs for powering
-single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. They are
-optimized for low BOM cost and compact solution footprint. BD71837MWV
-integrates 8 Buck regulators and 7 LDOs. BD71847MWV contains 6 Buck regulators
-and 6 LDOs.
-
-Datasheet for BD71837 is available at:
-https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
-Datasheet for BD71847 is available at:
-https://www.rohm.com/datasheet/BD71847AMWV/bd71847amwv-e
-
-Required properties:
- - compatible : Should be "rohm,bd71837" for bd71837
- "rohm,bd71847" for bd71847.
- - reg : I2C slave address.
- - interrupt-parent : Phandle to the parent interrupt controller.
- - interrupts : The interrupt line the device is connected to.
- - clocks : The parent clock connected to PMIC. If this is missing
- 32768 KHz clock is assumed.
- - #clock-cells : Should be 0.
- - regulators: : List of child nodes that specify the regulators.
- Please see ../regulator/rohm,bd71837-regulator.txt
-
-Optional properties:
-- clock-output-names : Should contain name for output clock.
-- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
-
-The BD718x7 supports two different HW states as reset target states. States
-are called as SNVS and READY. At READY state all the PMIC power outputs go
-down and OTP is reload. At the SNVS state all other logic and external
-devices apart from the SNVS power domain are shut off. Please refer to NXP
-i.MX8 documentation for further information regarding SNVS state. When a
-reset is done via SNVS state the PMIC OTP data is not reload. This causes
-power outputs that have been under SW control to stay down when reset has
-switched power state to SNVS. If reset is done via READY state the power
-outputs will be returned to HW control by OTP loading. Thus the reset
-target state is set to READY by default. If SNVS state is used the boot
-crucial regulators must have the regulator-always-on and regulator-boot-on
-properties set in regulator node.
-
-- rohm,short-press-ms : Short press duration in milliseconds
-- rohm,long-press-ms : Long press duration in milliseconds
-
-Configure the "short press" and "long press" timers for the power button.
-Values are rounded to what hardware supports (500ms multiple for short and
-1000ms multiple for long). If these properties are not present the existing
-configuration (from bootloader or OTP) is not touched.
-
-Example:
-
- /* external oscillator node */

+description: |
+ BD71847AMWV and BD71850MWV are programmable Power Management ICs for powering
+ single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is
+ optimized for low BOM cost and compact solution footprint. BD71847MWV and
+ BD71850MWV integrate 6 Buck regulators and 6 LDOs.
+ Datasheets are available at

-Required properties:

+description: |
+ List of regulators provided by this controller. BD71847 regulators node
+ should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at
+ Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml
+ Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
+ definition for each of these nodes is defined using the standard
+ binding for regulators at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+ Note that if BD71847 starts at RUN state you probably want to use
+ regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must
+ not be disabled by driver at startup. If BUCK5 is disabled at startup the
+ voltage monitoring for LDO5/LDO6 can cause PMIC to reset.
+
+#The valid names for BD71847 regulator nodes are:
+#BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6
+#LDO1, LDO2, LDO3, LDO4, LDO5, LDO6
