Subject: [v14 08/21] clk: mediatek: Add mtk_clk_simple_probe() to simplify clock providers
Date: Mon, 26 Jul 2021 18:57:06 +0800 [thread overview]
Message-ID: <20210726105719.15793-9-chun-jie.chen@mediatek.com> (raw)
In-Reply-To: <20210726105719.15793-1-chun-jie.chen@mediatek.com>
Most of subsystem clock providers only need to register clock gates
in their probe() function.
To reduce the duplicated code by add a generic function.
