From bcdd4efc1b6b8b98f30e127115f4bc7bbcd6f7ce Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 10 Oct 2008 15:58:13 +0100 Subject: mfd: Add initialisation callback for WM8350 Some functions of the WM8350 require board-specific initialisation on startup. Provide a callback to the WM8350 driver in platform data for platforms to use to configure the chip. Use of a callback allows platforms to control the ordering of initialisation which can be important.
