Subject: [PATCH] clk: rockchip: Use clk_hw_get_rate() in MMC phase calculation
Date: Tue, 7 May 2019 13:49:35 -0700 [thread overview]
Message-ID: <20190507204935.256982-1-dianders@chromium.org> (raw)
When calculating the MMC phase we can just use clk_hw_get_rate()
instead of clk_get_rate(). This avoids recalculating the rate.
