MT8195 VPPSYS0/1 will be probed by the compatible name in
the mtk-mmsys driver and then probe its own clock driver as
a platform driver.

mtk_alloc_clk_data() API changed a couple releases back. So:

API changed.

of_clk_add_provider(node, of_clk_hw_onecell_get, clk_data);
Same for the other driver.

This API is wrecked by a patch from AngeloGioacchino. Can you resend, or
tell me which device should be used here?

mtk_clk_register_gates(&pdev->dev, node, vpp0_clks, ......);
...with that change, for this patch:

P.S.: Next cleanup round will introduce mtk_clk_pdev_simple_probe()
Cheers,

Hi Stephen,
Thanks for your time and hlep.
Refer to
https://lore.kernel.org/lkml/20230120092053.182923-4-angelogioacchino.delregno@collabora.com/
, both clk-mt8195-vpp0/1 need to add "&pdev->dev" to the 1st param. in
the API to match the modification.
Regards,
Moudy
