From 0fc6bc0d6e953f6dd80c286c889d8d581e8f8d7a Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 22 Jan 2009 19:32:43 +0100 Subject: [PATCH] MIPS: RB532: Export rb532_gpio_set_func() This kernel symbol provides a way for drivers to switch on alternate function for a certain GPIO pin. Turning it off is done implicitly when changing the GPIO direction, as that would be fixed when using the given pin als alternate function.
