From 35ca98423a4c61decc20cd1d1e78a7fd7111e4db Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 22 Nov 2011 18:59:28 +0000 Subject: mfd: Add basic device tree binding for wm8994 Add a placeholder device tree binding for the wm8994 driver. At present the binding is essentially null as none of the platform data is supported, and at least some of that will depend on the pending regulator bindings.
