New since v1, putting in the same series as Arizona since they share the
same regulator binding.
Thanks,
Charles

-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,
- fll1-clk, fll1-lock, fll2-clk, fll2-lock, fll3-clk, fll3-lock,
- fllao-clk, fllao-lock,
- opclk, opclk-async, pwm1, pwm2, spdif,
- asrc1-in1-lock, asrc1-in2-lock, asrc2-in1-lock, asrc2-in2-lock,
- spkl-short-circuit, spkr-short-circuit, spk-shutdown,
- spk-overheat-shutdown, spk-overheat-warn,
- timer1-sts, timer2-sts, timer3-sts, timer4-sts, timer5-sts, timer6-sts,
- timer7-sts, timer8-sts,
- log1-fifo-ne, log2-fifo-ne, log3-fifo-ne, log4-fifo-ne, log5-fifo-ne,
- log6-fifo-ne, log7-fifo-ne, log8-fifo-ne,
-
- - bias-disable : disable pull-up and pull-down
- - bias-bus-hold : enable buskeeper
- - bias-pull-up : output is pulled-up
- - bias-pull-down : output is pulled-down
- - drive-push-pull : CMOS output
- - drive-open-drain : open-drain output
- - drive-strength : drive strength in mA. Valid values are 4 or 8
- - input-schmitt-enable : enable schmitt-trigger mode
- - input-schmitt-disable : disable schmitt-trigger mode
- - input-debounce : A value of 0 disables debounce, a value !=0 enables
- debounce
- - output-low : set the pin to output mode with low level
- - output-high : set the pin to output mode with high level
-
-Example:
-
-cs47l85@0 {
- compatible = "cirrus,cs47l85";
-
- pinctrl-names = "default";
- pinctrl-0 = <&cs47l85_defaults>;

-
- aif2 {
- groups = "aif2";
- function = "aif2";
- bias-bus-hold;
- };
-
- opclk {
- groups = "gpio1";
- function = "opclk";
