Subject: [PATCH v4 4/6] clk: rockchip: Export some clock common APIs for module drivers
Date: Mon, 14 Sep 2020 10:22:23 +0800 [thread overview]
Message-ID: <20200914022225.23613-5-zhangqing@rock-chips.com> (raw)
In-Reply-To: <20200914022225.23613-1-zhangqing@rock-chips.com>
This is used by the Rockchip clk driver, export it to allow that
driver to be compiled as a module.
