From 7583a213ec3bde3082547ee37ad96214513bc1cb Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 16 Sep 2011 13:21:47 +0100 Subject: mfd: Simulate active high IRQs with wm831x In order to ease system integration provide a simulation of active high IRQs on the GPIOs by polling the GPIO status when an IRQ is generated. This isn't ideal on several fronts and will miss initially active IRQs in the current implementation but it should work well for most cases.
