Subject: [PATCH 2/2] regulator: qcom_smd: Add PMR735a regulators
Date:   Wed,  9 Nov 2022 12:08:46 +0100
Message-Id: <20221109110846.45789-2-konrad.dybcio@linaro.org>
In-Reply-To: <20221109110846.45789-1-konrad.dybcio@linaro.org>
References: <20221109110846.45789-1-konrad.dybcio@linaro.org>

Precedence: bulk

PMR735a is already supported in the RPMH regulator driver, but
there are cases where it's bundled with SMD RPM SoCs. Port it over
to qcom_smd-regulator to enable usage in such cases.
