From 9d5cf5adcbb703a4c794232840c25a65a372c357 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 23 Feb 2007 20:52:19 +0100 Subject: [ARM] 4235/1: ns9xxx: declare the clock functions as "const" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch removes some "const"s that I introduced thinking they mean the same thing as the "const"s introduced here. So it fixes three warnings.

The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.
