Subject: [PATCH v2 21/34] rtc: mxc_rtc: remove cpu_is_xxx by using platform_device_id
Date: Thu, 20 Sep 2012 14:45:34 +0800 [thread overview]
Message-ID: <1348123547-31082-22-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1348123547-31082-1-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.
