Subject: [PATCH 15/26] soc: fsl: cpm1: qmc: Remove timeslots handling from setup_chan()
Date:   Tue, 25 Jul 2023 11:23:51 +0200
Message-ID: <20230725092417.43706-16-herve.codina@bootlin.com>
In-Reply-To: <20230725092417.43706-1-herve.codina@bootlin.com>

Timeslots setting is done at channel start() and stop().
There is no more need to do that during setup_chan().

Simply remove timeslot setting from setup_chan().
