From e2fccf5c15157218f0b6488168f98183f82c1eda Mon Sep 17 00:00:00 2001 From: Markus Pargmann Date: Mon, 14 Dec 2015 14:53:50 +0100 Subject: mfd: fsl-imx25-tsadc: Register touchscreen ADC driver This is the core driver for imx25 touchscreen/adc driver. The module has one shared ADC and two different conversion queues which use the ADC. The two queues are identical. Both can be used for general purpose ADC but one is meant to be used for touchscreens. This driver is the core which manages the central components and registers of the TSC/ADC unit. It manages the IRQs and forwards them to the correct components.
