From b103e0b3c52e6edb4839ccc961cf335ca6b88918 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 21 Jan 2011 13:26:46 +0000 Subject: mfd: Support configuration of WM831x /IRQ output in CMOS mode Provide platform data allowing the system to set the /IRQ pin into CMOS mode rather than the default open drain. The default value of this platform data reflects the default hardware configuration so there should be no change to existing users.
