From 805504abdc73cfc745a5fee3d616cdb24bb2a68c Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 27 Sep 2012 21:54:21 -0600 Subject: ARM: bcm2835: enable GPIO/pinctrl Enable GPIO and pinctrl in Kconfig. Add required for gpiolib. Instantiate the BCM2835 GPIO module in bcm2835.dtsi. Add a pinctrl definition to bcm2835-rpi-b.dts that sets up all of the board's required pinmux configuration. GPIO aren't specified; that's left to gpio_request().
