From: Yassine Oudjana <y.oudjana@protonmail.com> Add drivers for MT6735 apmixedsys, topckgen, infracfg and pericfg clock and reset controllers. These provide the base clocks and resets on the platform, and should be enough to bring up all essential blocks including PWRAP, MSDC and peripherals (UART, I2C, SPI).

It gets *even easier* than that! Check out this one: https://patchwork.kernel.org/project/linux-mediatek/patch/20230222092543.19187-5-angelogioacchino.delregno@collabora.com/ ...being part of: https://patchwork.kernel.org/project/linux-mediatek/list/?series=724004 So you can use simple_probe for MT6735's topckgen too! In this case, it would be... static const struct mtk_clk_desc topck_desc = { .clks = topckgen_muxes, .num_clks = ARRAY_SIZE(topckgen_muxes), .fixed_clks = topckgen_fixed_clks, .num_fixed_clks = ARRAY_SIZE(topckgen_fixed_clks), .factor_clks = topckgen_factors, .num_factor_clks = ARRAY_SIZE(topckgen_factors), .clk_lock = &mt6735_topckgen_lock, }; static const struct of_device_id of_match_mt6735_topckgen[] = { { .compatible = "mediatek,mt6735-topckgen", .data = &topck_desc }, { /* sentinel */ } }; MODULE_DEVICE_TABLE(of, of_match_mt6735_topckgen) ^^^^^ You're missing that on multiple clock drivers ;-) ...And you're replacing .probe(), .remove() callbacks with static struct platform_driver clk_mt6735_topckgen = { .probe = mtk_clk_simple_probe, .remove = mtk_clk_simple_remove, ...... Other than that, good job! After performing these changes, please make sure to mention the dependency on my last cleanup series on your cover letter for v4, so that maintainers will be aware of what to do. Your v4 smells like Reviewed-by tags all over. Keep up the great work!
