From 005044f41ed9884ee23d756a5950e38679d31cc7 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Tue, 21 Feb 2012 14:25:21 +0100 Subject: [PATCH 32/70] MIPS: lantiq: convert falcon debug uart to clkdev api On Falcon SoCs we have a secondary serial port that can be used to help debug the voice core. For the port to work several clocking bits need to be activated. We convert the code to clkdev api.
