Subject: [PATCH 1/4] ASoC: dt-bindings: document new symmetric-clock-role flag
Date: Fri,  2 Jun 2023 11:03:18 +0200	[thread overview]
Message-ID: <20230602090322.1876359-2-alvin@pqrs.dk> (raw)
In-Reply-To: <20230602090322.1876359-1-alvin@pqrs.dk>

From: Alvin Šipraga <alsi@bang-olufsen.dk>

The new flag specifies that both ends of the dai-link have the same
clock consumer/provider role. This should be used to describe hardware
where e.g. the CPU and codec both receive their bit- and frame-clocks
from an external source.
