Subject: [PATCH v13 06/10] soc: qcom: cpr-common: Add support for flat fuse adjustment
Date: Wed, 02 Aug 2023 14:37:46 +0200	[thread overview]
Message-ID: <20230217-topic-cpr3h-v13-6-d01cff1c54cf@linaro.org> (raw)
In-Reply-To: <20230217-topic-cpr3h-v13-0-d01cff1c54cf@linaro.org>

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

CPR3 makes use of post-calculation flat value adjustments. Add the
necessary bits to the common functions to support it.
