Subject: [PATCH 1/2] dt-bindings: misc: add binding for generic ripple counter
Date: Fri, 26 Feb 2021 15:14:10 +0100 [thread overview]
Message-ID: <20210226141411.2517368-2-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20210226141411.2517368-1-linux@rasmusvillemoes.dk>
While a ripple counter can not usually be interfaced with (directly)
from software, it may still be a crucial component in a board
layout. To prevent its input clock from being disabled by the clock
core because it apparently has no consumer, one needs to be able to
represent that consumer in DT.

+Generic ripple counter
+
+A ripple counter is a simple component that can for example be used to
+delay propagation of a signal.
+
+Required properties:
+- compatible: Must be "linux,ripple-ctr".
+- clocks: Input clock specifier. Refer to common clock bindings.
