Subject: [PATCH 08/13] m68k: m68328: use legacy_timer_tick()
Date:   Thu,  8 Oct 2020 17:46:46 +0200
Message-Id: <20201008154651.1901126-9-arnd@arndb.de>
In-Reply-To: <20201008154651.1901126-1-arnd@arndb.de>
References: <20201008154651.1901126-1-arnd@arndb.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

A couple of machines share the m68328 timer code that
is based on calling timer_interrupt(). Change these
to the new and slightly more generic legacy_timer_tick()
helper.
