From aa132ffb6b0a188c418f35da0750bdaf7aa34758 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Tue, 22 May 2018 10:52:36 +0300 Subject: input: touchscreen: resistive-adc-touch: add generic resistive ADC touchscreen This adds a generic resistive touchscreen (GRTS) driver, which is based on an IIO device (an ADC). It must be connected to the channels of an ADC to receive touch data. Then it will feed the data into the input subsystem where it registers an input device. It uses an IIO callback buffer to register to the IIO device Some parts of this patch are based on initial original work by Mohamed Jamsheeth Hajanajubudeen and Bandaru Venkateswara Swamy Signed-off-by: Eugen Hristev Acked-by: Dmitry Torokhov Signed-off-by: Jonathan Cameron --- drivers/input/touchscreen/Kconfig | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'drivers/input/touchscreen/Kconfig') diff --git a/drivers/input/touchscreen/Kconfig b/drivers/input/touchscreen/Kconfig index 32267c1afebc..66d1a220726a 100644 --- a/drivers/input/touchscreen/Kconfig +++ b/drivers/input/touchscreen/Kconfig @@ -92,6 +92,19 @@ config TOUCHSCREEN_AD7879_SPI To compile this driver as a module, choose M here: the module will be called ad7879-spi. +config TOUCHSCREEN_ADC + tristate "Generic ADC based resistive touchscreen" + depends on IIO + select IIO_BUFFER_CB + help + Say Y here if you want to use the generic ADC + resistive touchscreen driver. + + If unsure, say N (but it's safe to say "Y"). + + To compile this driver as a module, choose M here: the + module will be called resistive-adc-touch.ko. + config TOUCHSCREEN_AR1021_I2C tristate "Microchip AR1020/1021 i2c touchscreen" depends on I2C && OF -- cgit v1.2.3
