[PATCH v2 13/23] clk: mediatek: mt8173: Migrate pericfg/topckgen to mtk_clk_simple_probe()

AngeloGioacchino Del Regno
2022-12-23T09:44:30Z

Function mtk_clk_simple_probe() gained the ability to register multiple
clock types: migrate MT8173's pericfg and topckgen to this common
probe function to reduce duplication and code size.
