1 * Renesas R-Car GyroADC device driver
3 The GyroADC block is a reduced SPI block with up to 8 chipselect lines,
5 are sampled by the GyroADC block in a round-robin fashion and the result
6 presented in the GyroADC registers.
9 - compatible:	Should be "<soc-specific>", "renesas,rcar-gyroadc".
10                 The <soc-specific> should be one of:
11 		renesas,r8a7791-gyroadc - for the GyroADC block present
12 					  in r8a7791 SoC
13 		renesas,r8a7792-gyroadc - for the GyroADC with interrupt
15 - reg:		Address and length of the register set for the device
16 - clocks:	References to all the clocks specified in the clock-names
18 		Documentation/devicetree/bindings/clock/clock-bindings.txt.
19 - clock-names:	Shall contain "fck". The "fck" is the GyroADC block clock.
20 - power-domains: Must contain a reference to the PM domain, if available.
21 - #address-cells: Should be <1> (setting for the subnodes) for all ADCs
24 - #size-cells:	Should be <0> (setting for the subnodes)
26 Sub-nodes:
28 voltage for the GyroADC channels.
31 - compatible:	Should be either of:
33 			- Fujitsu MB88101A compatible mode,
35 			  round-robin fashion. One Fujitsu chip supplies four
36 			  GyroADC channels with data as it contains four ADCs
37 			  on the chip and thus for 4-channel operation, single
40 			  GyroADC, no demuxer is required. The data out line
42 			  the GyroADC.
44 			- TI ADCS7476 / TI ADC121 / ADI AD7476 compatible mode,
46 			  round-robin fashion. One TI/ADI chip supplies single
47 			  ADC channel with data, thus for 8-channel operation,
50 			  to the GyroADC, while MISO line of each TI/ADI ADC
51 			  connects to a shared input pin of the GyroADC.
53 			- Maxim MAX1162 / Maxim MAX11100 compatible mode,
55 			  round-robin fashion. One Maxim chip supplies single
56 			  ADC channel with data, thus for 8-channel operation,
59 			  to the GyroADC, while MISO line of each Maxim ADC
60 			  connects to a shared input pin of the GyroADC.
61 - reg:		Should be the number of the analog input. Should be present
63 - vref-supply:	Reference to the channel reference voltage regulator.
