Subject: [PATCH v2 6/6] clk: qcom: gpucc: Add Nord graphics clock controller support
Date: Tue, 21 Jul 2026 12:37:21 +0530 [thread overview]
Message-ID: <20260721-nords_mm_v1-v2-6-17e5a445a512@oss.qualcomm.com> (raw)
In-Reply-To: <20260721-nords_mm_v1-v2-0-17e5a445a512@oss.qualcomm.com>
Add support for the GPU clock controllers (GPUCC) on the Qualcomm
Nord platform.
The platform includes two GPU clock controller instances,GPUCC
and GPU2CC. Register support for both controllers, which provide
clocks required for the graphics subsystem.
