Subject: [PATCH] drivers: clk: make gpio-gated clock support optional
Date:   Thu, 19 Dec 2019 19:19:14 +0100
Message-Id: <20191219181914.6015-1-info@metux.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The gpio-gate-clock / gpio-mux-clock driver isn't used much,
just by a few ARM SoCs, so there's no need to always include
it unconditionally.

Thus make it optional, but keep it enabled by default.
