Subject: [v2 18/24] clk: mediatek: Add MT8195 vdosys1 clock support
Add MT8195 vdosys1 clock controller which provides clock gate
control for video system.
Signed-off-by: Chun-Jie Chen <chun-jie.chen@...iatek.com>
---
Integrate with mtk-mmsys driver which will pupulate device by
platform_device_register_data to start vdosys clock driver
