From b475f80b354a1915fda1b34070d712b825b60543 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Tue, 8 Nov 2016 12:58:58 +0100 Subject: iio: envelope-detector: ADC driver based on a DAC and a comparator The DAC is used to find the peak level of an alternating voltage input signal by a binary search using the output of a comparator wired to an interrupt pin. Like so: _ | \ input +------>-------|+ \ | \ .-------. | }---. | | | / | | dac|-->--|- / | | | |_/ | | | | | | | | irq|------<-------' | | '-------' Signed-off-by: Peter Rosin Acked-by: Thomas Gleixner Signed-off-by: Jonathan Cameron --- drivers/iio/adc/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/iio/adc/Makefile') diff --git a/drivers/iio/adc/Makefile b/drivers/iio/adc/Makefile index 96894b3..9391217 100644 --- a/drivers/iio/adc/Makefile +++ b/drivers/iio/adc/Makefile @@ -21,6 +21,7 @@ obj-$(CONFIG_BCM_IPROC_ADC) += bcm_iproc_adc.o obj-$(CONFIG_BERLIN2_ADC) += berlin2-adc.o obj-$(CONFIG_CC10001_ADC) += cc10001_adc.o obj-$(CONFIG_DA9150_GPADC) += da9150-gpadc.o +obj-$(CONFIG_ENVELOPE_DETECTOR) += envelope-detector.o obj-$(CONFIG_EXYNOS_ADC) += exynos_adc.o obj-$(CONFIG_FSL_MX25_ADC) += fsl-imx25-gcq.o obj-$(CONFIG_HI8435) += hi8435.o -- cgit v1.1
