Subject: [PATCH v4 11/16] clk: qcom: gcc-ipq806x: add additional freq for sdc table
Date:   Fri, 18 Feb 2022 00:56:58 +0100
Message-Id: <20220217235703.26641-12-ansuelsmth@gmail.com>
In-Reply-To: <20220217235703.26641-1-ansuelsmth@gmail.com>
References: <20220217235703.26641-1-ansuelsmth@gmail.com>

Precedence: bulk

Add additional freq supported for the sdc table. The ops are changed to
the floor_ops to handle a freq request of 52kHz where we need to provide
a freq of 51.2kHz instead for stability reason.
