Merge tag 'staging-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO driver updates from Greg KH:
 "Here is the big staging and IIO driver pull request for 5.7-rc1.

  We again end up deleting more code than we added here, thanks to
  finally getting rid of the old and obsolete wireless USB stuff, and
  the exfat code (which is coming in again through the vfs tree in a
  much cleaner version).

  But some code does come back, with the octeon drivers being found to
  actually be used in the wild, so those deletions are now reverted.

  Other than those major things, just loads and loads of tiny checkpatch
  cleanups all over the place, along with new IIO drivers and fixes.

  All have been in linux-next with no reported issues"

[ Stephen Rothwell points out some reported issues due to merge conflicts ]

-STMicroelectronics STM32 ADC device driver
-
-STM32 ADC is a successive approximation analog-to-digital converter.
-It has several multiplexed input channels. Conversions can be performed
-in single, continuous, scan or discontinuous mode. Result of the ADC is
-stored in a left-aligned or right-aligned 32-bit data register.
-Conversions can be launched in software or using hardware triggers.
-
-The analog watchdog feature allows the application to detect if the input
-voltage goes beyond the user-defined, higher or lower thresholds.
-
-Each STM32 ADC block can have up to 3 ADC instances.
-
-Each instance supports two contexts to manage conversions, each one has its
-own configurable sequence and trigger:
-- regular conversion can be done in sequence, running in background
-- injected conversions have higher priority, and so have the ability to
-  interrupt regular conversion sequence (either triggered in SW or HW).
-  Regular sequence is resumed, in case it has been interrupted.
-
-Contents of a stm32 adc root node:
------------------------------------
-Required properties:
-- compatible: Should be one of:
-  "st,stm32f4-adc-core"
-  "st,stm32h7-adc-core"
-  "st,stm32mp1-adc-core"
-- reg: Offset and length of the ADC block register set.
-- interrupts: One or more interrupts for ADC block. Some parts like stm32f4
-  and stm32h7 share a common ADC interrupt line. stm32mp1 has two separate
-  interrupt lines, one for each ADC within ADC block.
-- clocks: Core can use up to two clocks, depending on part used:
-  - "adc" clock: for the analog circuitry, common to all ADCs.
-    It's required on stm32f4.
-    It's optional on stm32h7.
-  - "bus" clock: for registers access, common to all ADCs.
-    It's not present on stm32f4.
-    It's required on stm32h7.
-- clock-names: Must be "adc" and/or "bus" depending on part used.
-- interrupt-controller: Identifies the controller node as interrupt-parent
-- vdda-supply: Phandle to the vdda input analog voltage.
-- vref-supply: Phandle to the vref input analog reference voltage.
-- #interrupt-cells = <1>;
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- A pinctrl state named "default" for each ADC channel may be defined to set
-  inX ADC pins in mode of operation for analog input on external pin.
-- booster-supply: Phandle to the embedded booster regulator that can be used
-  to supply ADC analog input switches on stm32h7 and stm32mp1.
-- vdd-supply: Phandle to the vdd input voltage. It can be used to supply ADC
-  analog input switches on stm32mp1.
-- st,syscfg: Phandle to system configuration controller. It can be used to
-  control the analog circuitry on stm32mp1.
-- st,max-clk-rate-hz: Allow to specify desired max clock rate used by analog
-  circuitry.
-
-Contents of a stm32 adc child node:
------------------------------------
-An ADC block node should contain at least one subnode, representing an
-ADC instance available on the machine.
-
-Required properties:
-- compatible: Should be one of:
-  "st,stm32f4-adc"
-  "st,stm32h7-adc"
-  "st,stm32mp1-adc"
-- reg: Offset of ADC instance in ADC block (e.g. may be 0x0, 0x100, 0x200).
-- clocks: Input clock private to this ADC instance. It's required only on
-  stm32f4, that has per instance clock input for registers access.
-- interrupts: IRQ Line for the ADC (e.g. may be 0 for adc@0, 1 for adc@100 or
-  2 for adc@200).
-- st,adc-channels: List of single-ended channels muxed for this ADC.
-  It can have up to 16 channels on stm32f4 or 20 channels on stm32h7, numbered
-  from 0 to 15 or 19 (resp. for in0..in15 or in0..in19).
-- st,adc-diff-channels: List of differential channels muxed for this ADC.
-  Depending on part used, some channels can be configured as differential
-  instead of single-ended (e.g. stm32h7). List here positive and negative
-  inputs pairs as <vinp vinn>, <vinp vinn>,... vinp and vinn are numbered
-  from 0 to 19 on stm32h7)
-  Note: At least one of "st,adc-channels" or "st,adc-diff-channels" is required.
-  Both properties can be used together. Some channels can be used as
-  single-ended and some other ones as differential (mixed). But channels
-  can't be configured both as single-ended and differential (invalid).
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in
-  Documentation/devicetree/bindings/iio/iio-bindings.txt
-
-Optional properties:
-- dmas: Phandle to dma channel for this ADC instance.
-  See ../../dma/dma.txt for details.
-- dma-names: Must be "rx" when dmas property is being used.
-- assigned-resolution-bits: Resolution (bits) to use for conversions. Must
-  match device available resolutions:
-  * can be 6, 8, 10 or 12 on stm32f4
-  * can be 8, 10, 12, 14 or 16 on stm32h7
-  Default is maximum resolution if unset.
-- st,min-sample-time-nsecs: Minimum sampling time in nanoseconds.
-  Depending on hardware (board) e.g. high/low analog input source impedance,
-  fine tune of ADC sampling time may be recommended.
-  This can be either one value or an array that matches 'st,adc-channels' list,
-  to set sample time resp. for all channels, or independently for each channel.
-
-Example:
-	adc: adc@40012000 {
-		compatible = "st,stm32f4-adc-core";
-		reg = <0x40012000 0x400>;
-		interrupts = <18>;
-		clocks = <&rcc 0 168>;
-		clock-names = "adc";
-		vref-supply = <&reg_vref>;
-		interrupt-controller;
-		pinctrl-names = "default";
-		pinctrl-0 = <&adc3_in8_pin>;
-
-		#interrupt-cells = <1>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		adc@0 {
-			compatible = "st,stm32f4-adc";
-			#io-channel-cells = <1>;
-			reg = <0x0>;
-			clocks = <&rcc 0 168>;
-			interrupt-parent = <&adc>;
-			interrupts = <0>;

-			dmas = <&dma2 0 0 0x400 0x0>;
-			dma-names = "rx";
-			assigned-resolution-bits = <8>;
-		};
-		...
-		other adc child nodes follow...
-	};
-
-Example to setup:
-- channel 1 as single-ended
-- channels 2 & 3 as differential (with resp. 6 & 7 negative inputs)
-
-	adc: adc@40022000 {
-		compatible = "st,stm32h7-adc-core";
-		...
-		adc1: adc@0 {
-			compatible = "st,stm32h7-adc";
