From b505ff5e7291cca6379549297e3852ce3622d550 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Fri, 18 Jun 2010 11:09:59 -0600 Subject: of: kill struct of_device Now that the device tree node pointer has been moved out of struct of_device and into the common struct device, there isn't anything unique about of_device anymore. In fact, there isn't much need for a separate of_bus when all busses have access to OF style probing. arch/powerpc and arch/microblaze are moving away from using the of_bus and using the regular platform bus instead for mmio devices. This patch makes of_device the same as platform_device as a stepping stone in migrating of_platform_drivers over to the platform bus. Signed-off-by: Grant Likely Acked-by: David S.
