7 		"ti,am3359-tscadc" for AM335x/AM437x SoCs
8 		"ti,am654-tscadc", "ti,am3359-tscadc" for AM654 SoCs
9 - child "tsc"
10 	compatible: Should be "ti,am3359-tsc".
13 	ti,x-plate-resistance: X plate resistance
14 	ti,coordinate-readouts: The sequencer supports a total of 16
22 				remaining 4 can be used by the ADC.
23 	ti,wire-config: Different boards could have a different order for
32 - child "adc"
34 		    "ti,am3359-adc" for AM335x/AM437x SoCs
35 		    "ti,am654-adc", "ti,am3359-adc" for AM654 SoCs
36 	ti,adc-channels: List of analog inputs available for ADC.
40 - child "tsc"
41 	ti,charge-delay: Length of touch screen charge delay step in terms of
42 			 ADC clock cycles. Charge delay value should be large
43 			 in order to avoid false pen-up events. This value
45 			 kept as low as possible, while avoiding false pen-up
47 			 increase value until false pen-up events are avoided.
48 			 The pen-up detection happens immediately after the
53 - child "adc"
54 	ti,chan-step-opendelay: List of open delays for each channel of
55 				ADC in the order of ti,adc-channels. The
56 				value corresponds to the number of ADC
59 				sending the start of ADC conversion.
61        ti,chan-step-sampledelay: List of sample delays for each channel
62 				  of ADC in the order of ti,adc-channels.
64 				  ADC clock cycles to sample (to hold
67        ti,chan-step-avg: Number of averages to be performed for each
68 			  channel of ADC. If average is 16 then input
71 			  by ADC to generate a sample. Valid range is 0
