Subject: [PATCH v4 08/10] interconnect: qcom: sdm660: Set AB/IB coefficients
Date: Fri, 25 Aug 2023 17:38:30 +0200	[thread overview]
Message-ID: <20230726-topic-icc_coeff-v4-8-c04b60caa467@linaro.org> (raw)
In-Reply-To: <20230726-topic-icc_coeff-v4-0-c04b60caa467@linaro.org>

Some buses and nodes need additional manual adjustments atop the usual
calculations. Fill in the missing coefficients.
