Subject: [PATCH v2 05/11] clk: qcom: gcc-sc8180x: Enable runtime PM support
Date: Thu, 12 Mar 2026 08:12:10 -0300	[thread overview]
Message-ID: <20260312112321.370983-6-val@packett.cool> (raw)
In-Reply-To: <20260312112321.370983-1-val@packett.cool>

The GCC block on SC8180X is powered by the CX rail. We need to ensure
that it's enabled to prevent unwanted power collapse.

Enable runtime PM to keep the power flowing only when necessary.
