Subject: [PATCH 2/3] i2c: qcom-cci: Add missing cci_clk_rate for msm8953
Date: Tue, 21 Jul 2026 16:58:20 +0200 [thread overview]
Message-ID: <20260721-cci-clk-fix-v1-2-5eae78700da8@oss.qualcomm.com> (raw)
In-Reply-To: <20260721-cci-clk-fix-v1-0-5eae78700da8@oss.qualcomm.com>
The msm8953 CCI data was added after cci_clk_rate was removed from the
driver, so it never got a clock rate entry. The DT assigns 19.2 MHz to
GCC_CAMSS_CCI_CLK and the hw_params values match those of v1/v1.5 which
were also calibrated for 19.2 MHz.
Fixes: d202341d9b0c ("i2c: qcom-cci: Add msm8953 compatible")
