Subject: [PATCH 06/26] soc: fsl: cpm1: qmc: Introduce available timeslots masks
Date: Tue, 25 Jul 2023 11:23:42 +0200 [thread overview]
Message-ID: <20230725092417.43706-7-herve.codina@bootlin.com> (raw)
In-Reply-To: <20230725092417.43706-1-herve.codina@bootlin.com>
Available timeslots masks define timeslots available for the related
channel. These timeslots are defined by the QMC binding.
Timeslots used are initialized to available timeslots but can be a
subset of available timeslots.
This prepares the dynamic timeslots management (ie. changing timeslots
at runtime).
