From 96b1b29d37b0ca3ecd424a1fe301406cf525fc04 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 21 Jun 2012 21:40:38 -0600 Subject: ARM: OMAP2+: HDQ1W: use omap_device Convert the old-style device registration code for HDQ1W to use omap_device. This will allow the driver to be converted to use PM runtime and to take advantage of the OMAP IP block management infrastructure (hwmod, PM, etc.). A side benefit of this conversion is that it also makes the HDQ device available on OMAP2420. The previous code only enabled it on 2430 and 3430.

Also note that we need to only build this code if MMC_OMAP is selected, so change Makefile accordingly and place it near the MMC_OMAP_HS in the Makefile.
