+Subject: [RFC,1/3] ARM: gemini: get platform to build again
+Date: Fri, 04 Jan 2013 15:30:38 -0000
+From: Arnd Bergmann <arnd@arndb.de>
+X-Patchwork-Id: 1933501
+Message-Id: <1357313440-20092-1-git-send-email-arnd@arndb.de>
+To: Hans Ulli Kroll <ulli.kroll@googlemail.com>
+Cc: Russell King <rmk+kernel@arm.linux.org.uk>, Arnd Bergmann <arnd@arndb.de>, 
+ Florian Fainelli <florian@openwrt.org>,
+ linux-arm-kernel@lists.infradead.org
+
+There is no defconfig file for gemini, which has lead to a lot
+of bitrot. This makes the broken board files, the gpio implementation
+and the reset logic work again, and fixes the build warnings
+that got introduced with the changes to the readl/writel prototypes.
