Subject: [PATCH v5 09/15] clk: qcom: clk-rcg: add clk_rcg_floor_ops ops
Date: Thu, 24 Feb 2022 17:48:25 +0100 [thread overview]
Message-ID: <20220224164831.21475-10-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20220224164831.21475-1-ansuelsmth@gmail.com>
Add clk_rcg_floor_ops for clock that can't provide a stable freq and
require to use a floor freq to provide the requested frequency.
