Subject: [PATCH v8 23/26] MIPS: GCW0: Move clocksource to TCU channel 2
Date:   Wed, 12 Dec 2018 23:13:17 +0100
Message-Id: <20181212221317.19335-1-paul@crapouillou.net>
In-Reply-To: <20181212220922.18759-1-paul@crapouillou.net>
References: <20181212220922.18759-1-paul@crapouillou.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The TCU channel 1, which is the default for the clocksource, is used as
PWM on the GCW Zero as it drives the backlight. Therefore we must use a
different TCU channel for the clocksource.
