Subject: [PATCH 30/34] video: imxfb: remove mach/hardware.h inclusion
Date: Mon, 17 Sep 2012 13:34:59 +0800 [thread overview]
Message-ID: <1347860103-4141-31-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1347860103-4141-1-git-send-email-shawn.guo@linaro.org>
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.
