From e69dc9a91eeb0387e08d8e1d0e576c88b28902fc Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Sun, 16 Sep 2012 19:59:53 +0800 Subject: [PATCH] video: imxfb: remove cpu_is_xxx by using platform_device_id It changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type, and updates the platform code accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.
