-* AT91's Analog to Digital Converter (ADC)
-
-Required properties:
- - compatible: Should be "atmel,<chip>-adc"
- <chip> can be "at91sam9260", "at91sam9g45" or "at91sam9x5"
- - reg: Should contain ADC registers location and length
- - interrupts: Should contain the IRQ line for the ADC
- - atmel,adc-channels-used: Bitmask of the channels muxed and enabled for this
- device
- - atmel,adc-startup-time: Startup Time of the ADC in microseconds as
- defined in the datasheet
- - atmel,adc-vref: Reference voltage in millivolts for the conversions
- - atmel,adc-res: List of resolutions in bits supported by the ADC. List size
- must be two at least.
- - atmel,adc-res-names: Contains one identifier string for each resolution
- in atmel,adc-res property. "lowres" and "highres"
- identifiers are required.
-
-Optional properties:
- - atmel,adc-use-external: Boolean to enable the external triggers
- - atmel,adc-use-res: String corresponding to an identifier from
- atmel,adc-res-names property. If not specified, the highest
- resolution will be used.
- - atmel,adc-sleep-mode: Boolean to enable sleep mode when no conversion
- - atmel,adc-sample-hold-time: Sample and Hold Time in microseconds
- - atmel,adc-ts-wires: Number of touchscreen wires. Should be 4 or 5. If this
- value is set, then the adc driver will enable touchscreen
- support.
- NOTE: when adc touchscreen is enabled, the adc hardware trigger will be
- disabled. Since touchscreen will occupy the trigger register.
- - atmel,adc-ts-pressure-threshold: a pressure threshold for touchscreen. It
- makes touch detection more precise.
-
-Optional trigger Nodes:
- - Required properties:
- * trigger-name: Name of the trigger exposed to the user
- * trigger-value: Value to put in the Trigger register
- to activate this trigger
- - Optional properties:
- * trigger-external: Is the trigger an external trigger?
-
-Examples:
-adc0: adc@...b0000 {
- compatible = "atmel,at91sam9260-adc";
- reg = <0xfffb0000 0x100>;
- interrupts = <20 4>;
- atmel,adc-channels-used = <0xff>;
- atmel,adc-startup-time = <40>;
- atmel,adc-use-external;
- atmel,adc-vref = <3300>;
- atmel,adc-res = <8 10>;
- atmel,adc-res-names = "lowres", "highres";
- atmel,adc-use-res = "lowres";
-
- trigger0 {
- trigger-name = "external-rising";
- trigger-value = <0x1>;
- trigger-external;
- };
- trigger1 {
- trigger-name = "external-falling";
