* ROHM BD71837 Power Management Integrated Circuit bindings
BD71837MWV is a programmable Power Management IC 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. It integrates 8 Buck
egulators and 7 LDOs to provide all the power rails required by the SoC and
the commonly used peripherals.

Cirrus Logic Madera class audio codecs pinctrl driver
The Cirrus Logic Madera codecs provide a number of GPIO functions for
interfacing to external hardware and to provide logic outputs to other devices.
Certain groups of GPIO pins also have an alternate function, normally as an
audio interface.
The set of available GPIOs, functions and alternate function groups differs
between codecs so refer to the datasheet for the codec for further information
on what is supported on that device.
The properties for this driver exist within the parent MFD driver node.
See also
the core bindings for the parent MFD driver:
Documentation/devicetree/bindings/mfd/madera.txt
the generic pinmix bindings:
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
Required properties of parent mfd node:
- pinctrl-names : must be "default"
- pinctrl-0 : a phandle to the node containing the subnodes containing default
configurations
Required subnodes:
One subnode is required to contain the default settings. It contains an
arbitrary number of configuration subnodes, one for each group or pin
configuration you want to apply as a default.
Required properties of configuration subnodes:
- groups : name of one pin group to configure. One of:
aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,
dmic4, dmic5, dmic6,
gpio1, gpio2, ..., gpio40
The gpioN groups select the single pin of this name for configuration
Optional properties of configuration subnodes:
Any configuration option not explicitly listed in the dts will be left at
chip default setting.
- function : name of function to assign to this group. One of:
aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,
dmic3, dmic4, dmic5, dmic6,
io, dsp-gpio, irq1, irq2,

debounce
