Subject: [PATCH v3 3/3] arm64: dts: qcom: sm8750: Add GPU clock & IOMMU nodes
Date: Fri, 20 Feb 2026 11:24:22 +0530	[thread overview]
Message-ID: <20260220-gpucc_sm8750_v2-v3-3-6c5408564c3c@oss.qualcomm.com> (raw)
In-Reply-To: <20260220-gpucc_sm8750_v2-v3-0-6c5408564c3c@oss.qualcomm.com>

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Add the GPU_CC and GX_CC (brand new! as far as we're concerned, this
is simply a separate block housing the GX GDSC) nodes, required to
power up the graphics-related hardware.

Make use of it by enabling the associated IOMMU as well. The GPU itself
needs some more work and will be enabled later.
