From 7fde1484af21f9668e9575bd8a119ebc4fe6fe42 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Tue, 8 Nov 2016 12:58:56 +0100 Subject: iio: dpot-dac: DAC driver based on a digital potentiometer It is assumed that the dpot is used as a voltage divider between the current dpot wiper setting and the maximum resistance of the dpot. The divided voltage is provided by a vref regulator. .------. .-----------. | | | vref |--' .---. | regulator |--. | | '-----------' | | d | | | p | | | o | wiper | | t |<---------+ | | | | '---' dac output voltage | | '------+------------+ Signed-off-by: Peter Rosin Signed-off-by: Jonathan Cameron --- drivers/iio/dac/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/iio/dac/Makefile') diff --git a/drivers/iio/dac/Makefile b/drivers/iio/dac/Makefile index 27642bbf75f2..f01bf4a99867 100644 --- a/drivers/iio/dac/Makefile +++ b/drivers/iio/dac/Makefile @@ -22,6 +22,7 @@ obj-$(CONFIG_AD5686) += ad5686.o obj-$(CONFIG_AD7303) += ad7303.o obj-$(CONFIG_AD8801) += ad8801.o obj-$(CONFIG_CIO_DAC) += cio-dac.o +obj-$(CONFIG_DPOT_DAC) += dpot-dac.o obj-$(CONFIG_LPC18XX_DAC) += lpc18xx_dac.o obj-$(CONFIG_M62332) += m62332.o obj-$(CONFIG_MAX517) += max517.o -- cgit v1.2.3
