Subject: [PATCH v2 3/6] remoteproc: qcom_q6v5_mss: Use mss as regulator for MSM8953
Date: Tue, 29 Sep 2026 20:28:32 +0200	[thread overview]
Message-ID: <20260929-sdm632-rpmpd-v2-3-97ef8858161b@mainlining.org> (raw)
In-Reply-To: <20260929-sdm632-rpmpd-v2-0-97ef8858161b@mainlining.org>

On MSM8953 MSS regulators is controlled using the voltages rather than
performance levels. Correct DT definition and model the MSS as a
regulator rather than a power domain
