+Subject: [PATCH V2] ARM: BCM5301X: select GPIOLIB as optional
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+All routers (or 99% of them) based on BCM5301X use GPIOs to control LEDs
+and buttons.
+
+Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
+---
+V2: Don't select GPIOLIB. We may still think about making it default at
+ some point, but we dont' really require it to boot successfully.

+Subject: [PATCH] bcma: gpio: use ChipCommon GPIO IRQ on BCM47XX arch only
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GPIOs can be also used on bcm53xx, however this arch requires different
+implementation of IRQ support. It uses different IRQ number (117) and
+different masks & acking.
