Subject: [PATCH v5 7/9] clk: cs2000-cp: make clock skip setting configurable
Date: Wed, 1 Sep 2021 11:36:29 +0200 [thread overview]
Message-ID: <20210901093631.1403278-8-daniel@zonque.org> (raw)
In-Reply-To: <20210901093631.1403278-1-daniel@zonque.org>
The clock skip function of this chip is not necessarily desirable in
all hardware appliances. This patch makes the feature configurable
through a device-tree property.
