Subject: [RFC PATCH 15/18] OMAP: GPIO: cleanup gpio_show_rev
Date: Fri, 22 Apr 2011 16:38:29 +0530	[thread overview]
Message-ID: <1303470512-19671-16-git-send-email-charu@ti.com> (raw)
In-Reply-To: <1303470512-19671-1-git-send-email-charu@ti.com>

Remove cpu_is* checks from omap_gpio_show_rev.

Also display GPIO IP version only once as it is not
required to print the IP version of all the banks as
they are the same.
