From 9b7a69d0bd2bb7bcf1b811f273a27be929520b61 Mon Sep 17 00:00:00 2001 From: Herve Codina Date: Tue, 5 Dec 2023 16:21:04 +0100 Subject: soc: fsl: cpm1: qmc: Introduce available timeslots masks 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).
