Subject: [PATCH v5 22/27] clk: mediatek: Add MT8196 disp1 clock support
Date: Fri, 29 Aug 2025 11:19:08 +0200 [thread overview]
Message-ID: <20250829091913.131528-23-laura.nao@collabora.com> (raw)
In-Reply-To: <20250829091913.131528-1-laura.nao@collabora.com>
Add support for the MT8196 disp1 clock controller, which provides clock
gate control for the display system. It is integrated with the mtk-mmsys
driver, which registers the disp1 clock driver via
platform_device_register_data().
