-* Renesas R-Car GyroADC device driver
-
-The GyroADC block is a reduced SPI block with up to 8 chipselect lines,
-which supports the SPI protocol of a selected few SPI ADCs. The SPI ADCs
-are sampled by the GyroADC block in a round-robin fashion and the result
-presented in the GyroADC registers.
-
-Required properties:
-- compatible:	Should be "<soc-specific>", "renesas,rcar-gyroadc".
-                The <soc-specific> should be one of:
-		renesas,r8a7791-gyroadc - for the GyroADC block present
-					  in r8a7791 SoC
-		renesas,r8a7792-gyroadc - for the GyroADC with interrupt
-					  block present in r8a7792 SoC
-- reg:		Address and length of the register set for the device
-- clocks:	References to all the clocks specified in the clock-names
-		property as specified in
-		Documentation/devicetree/bindings/clock/clock-bindings.txt.
-- clock-names:	Shall contain "fck". The "fck" is the GyroADC block clock.
-- power-domains: Must contain a reference to the PM domain, if available.
-- #address-cells: Should be <1> (setting for the subnodes) for all ADCs
-		except for "fujitsu,mb88101a". Should be <0> (setting for
-		only subnode) for "fujitsu,mb88101a".
-- #size-cells:	Should be <0> (setting for the subnodes)
-
-Sub-nodes:
-You must define subnode(s) which select the connected ADC type and reference
-voltage for the GyroADC channels.
-
-Required properties for subnodes:
-- compatible:	Should be either of:
-		"fujitsu,mb88101a"
-			- Fujitsu MB88101A compatible mode,
-			  12bit sampling, up to 4 channels can be sampled in
-			  round-robin fashion. One Fujitsu chip supplies four
-			  GyroADC channels with data as it contains four ADCs
-			  on the chip and thus for 4-channel operation, single
-			  MB88101A is required. The Cx chipselect lines of the
-			  MB88101A connect directly to two CHS lines of the
-			  GyroADC, no demuxer is required. The data out line
-			  of each MB88101A connects to a shared input pin of
-			  the GyroADC.
-		"ti,adcs7476" or "ti,adc121" or "adi,ad7476"
-			- TI ADCS7476 / TI ADC121 / ADI AD7476 compatible mode,
-			  15bit sampling, up to 8 channels can be sampled in
-			  round-robin fashion. One TI/ADI chip supplies single
-			  ADC channel with data, thus for 8-channel operation,
-			  8 chips are required. A 3:8 chipselect demuxer is
-			  required to connect the nCS line of the TI/ADI chips
-			  to the GyroADC, while MISO line of each TI/ADI ADC
-			  connects to a shared input pin of the GyroADC.
-		"maxim,max1162" or "maxim,max11100"
-			- Maxim MAX1162 / Maxim MAX11100 compatible mode,
-			  16bit sampling, up to 8 channels can be sampled in
-			  round-robin fashion. One Maxim chip supplies single
-			  ADC channel with data, thus for 8-channel operation,
-			  8 chips are required. A 3:8 chipselect demuxer is
-			  required to connect the nCS line of the MAX chips
-			  to the GyroADC, while MISO line of each Maxim ADC
-			  connects to a shared input pin of the GyroADC.
-- reg:		Should be the number of the analog input. Should be present
-		for all ADCs except "fujitsu,mb88101a".
-- vref-supply:	Reference to the channel reference voltage regulator.

-Example:
-	vref_max1162: regulator-vref-max1162 {
-		compatible = "regulator-fixed";
-
-		regulator-name = "MAX1162 Vref";
-		regulator-min-microvolt = <4096000>;
-		regulator-max-microvolt = <4096000>;
