Subject: [PATCH RESEND v4 7/9] clk: cs2000-cp: make clock skip setting configurable
Date: Tue, 25 Jan 2022 10:33:34 +0100 [thread overview]
Message-ID: <20220125093336.226787-8-daniel@zonque.org> (raw)
In-Reply-To: <20220125093336.226787-1-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.
