This series migrates most MediaTek clock drivers to the common probe/remove helpers provided by the MTK clock framework. Key changes: - Fix memory leaks on module removal caused by missing platform_set_drvdata() calls (patches 1-6). - Add missing MODULE_DEVICE_TABLE() (patches 7, 8). - Add missing support for cpumux, PLL, pllfh, and sub-device auto-population to the common helpers (patches 9-12). - Convert all compatible clock drivers to use struct mtk_clk_desc and mtk_clk_simple_probe/remove (patches 13-32). The memory leak and MODULE_DEVICE_TABLE() fixes are split from the migration patches to allow backporting to stable. Drivers not converted: - MT6765 apmixedsys: requires direct register init. - MT6795 apmixedsys: uses mtk_clk_register_ref2usb_tx(). - MT7629 eth/sgmiisys: uses a hacked probe sequence (multi-instance sgmii gates). - MT8173 apmixedsys: uses mtk_clk_register_ref2usb_tx() and custom divider registration. - MT8188/MT8195 topckgen: call devm_clk_hw_register_mux() and register a notifier. - MT8196 vlpckgen: requires direct register init. - MT8365 apmixedsys: uses devm_clk_hw_register_gate(). Patches 1-6 are based on "[PATCH v2 0/6] clk: mediatek: fix memory leak on module removal" (In addition fixed a compilation error in mt8173-infracfg) https://lore.kernel.org/linux-mediatek/[email protected]/ Patch 9 is based on "[PATCH 1/3] clk: mediatek: clk-mtk: Add cpumux support to common probe/remove helpers" https://lore.kernel.org/lkml/[email protected]/ Akari Tsuyukusa (32): clk: mediatek: mt2712: fix memory leak on module removal clk: mediatek: mt6795: fix memory leak on module removal clk: mediatek: mt7622: fix memory leak on module removal clk: mediatek: mt8135: fix memory leak on module removal clk: mediatek: mt8173: fix memory leak on module removal clk: mediatek: mt8192: fix memory leak on module removal clk: mediatek: mt6735: Add missing MODULE_DEVICE_TABLE() clk: mediatek: mt7988-apmixed: Add missing MODULE_DEVICE_TABLE() clk: mediatek: Add cpumux support to common probe/remove helpers clk: mediatek: Add PLL support to common probe/remove helpers clk: mediatek: Add auto-population of sub-devices support in simple probe clk: mediatek: Add pllfh support to common probe/remove helpers clk: mediatek: mt2701: Switch to common probe/remove helpers clk: mediatek: mt2712-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt6735-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt6779: Switch to common probe/remove helpers clk: mediatek: mt6795: Switch to common probe/remove helpers clk: mediatek: mt6797: Switch to common probe/remove helpers clk: mediatek: mt7622: Switch to common probe/remove helpers clk: mediatek: mt7981-apmixed: Switch to common probe/remove helpers clk: mediatek: mt7986-apmixed: Switch to common probe/remove helpers clk: mediatek: mt7988-apmixed: Switch to common probe/remove helpers clk: mediatek: mt8135-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt8167-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt8173-infracfg: Switch to common probe/remove helpers clk: mediatek: mt8183: Switch to common probe/remove helpers clk: mediatek: mt8186-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt8188-apmixedsys: Switch to common probe/remove helpers clk: mediatek: mt8192: Switch to common probe/remove helpers clk: mediatek: mt8195: Switch to common probe/remove helpers clk: mediatek: mt8196: Switch to common probe/remove helpers clk: mediatek: mt8516-apmixedsys: Switch to common probe/remove helpers drivers/clk/mediatek/Kconfig | 34 +-- drivers/clk/mediatek/clk-mt2701-aud.c | 35 +-- drivers/clk/mediatek/clk-mt2701.c | 233 +++++-------------- drivers/clk/mediatek/clk-mt2712-apmixedsys.c | 48 +--- drivers/clk/mediatek/clk-mt6735-apmixedsys.c | 48 +--- drivers/clk/mediatek/clk-mt6735-imgsys.c | 1 + drivers/clk/mediatek/clk-mt6735-mfgcfg.c | 1 + drivers/clk/mediatek/clk-mt6735-vdecsys.c | 1 + drivers/clk/mediatek/clk-mt6735-vencsys.c | 1 + drivers/clk/mediatek/clk-mt6779.c | 124 ++-------- drivers/clk/mediatek/clk-mt6795-apmixedsys.c | 2 + drivers/clk/mediatek/clk-mt6795-infracfg.c | 70 +----- drivers/clk/mediatek/clk-mt6795-pericfg.c | 71 +----- drivers/clk/mediatek/clk-mt6797.c | 140 ++--------- drivers/clk/mediatek/clk-mt7622-apmixedsys.c | 60 +---- drivers/clk/mediatek/clk-mt7622-aud.c | 35 +-- drivers/clk/mediatek/clk-mt7622-infracfg.c | 70 +----- drivers/clk/mediatek/clk-mt7981-apmixed.c | 37 +-- drivers/clk/mediatek/clk-mt7986-apmixed.c | 37 +-- drivers/clk/mediatek/clk-mt7988-apmixed.c | 40 +--- drivers/clk/mediatek/clk-mt8135-apmixedsys.c | 48 +--- drivers/clk/mediatek/clk-mt8167-apmixedsys.c | 50 +--- drivers/clk/mediatek/clk-mt8173-apmixedsys.c | 2 + drivers/clk/mediatek/clk-mt8173-infracfg.c | 98 ++------ drivers/clk/mediatek/clk-mt8183-apmixedsys.c | 51 +--- drivers/clk/mediatek/clk-mt8183-audio.c | 26 +-- drivers/clk/mediatek/clk-mt8186-apmixedsys.c | 59 +---- drivers/clk/mediatek/clk-mt8188-apmixedsys.c | 60 +---- drivers/clk/mediatek/clk-mt8192-apmixedsys.c | 67 ++---- drivers/clk/mediatek/clk-mt8192-aud.c | 26 +-- drivers/clk/mediatek/clk-mt8195-apmixedsys.c | 67 +----- drivers/clk/mediatek/clk-mt8195-apusys_pll.c | 49 +--- drivers/clk/mediatek/clk-mt8196-apmixedsys.c | 67 +----- drivers/clk/mediatek/clk-mt8196-mcu.c | 96 +++----- drivers/clk/mediatek/clk-mt8196-mfg.c | 84 ++----- drivers/clk/mediatek/clk-mt8516-apmixedsys.c | 42 +--- drivers/clk/mediatek/clk-mtk.c | 76 +++++- drivers/clk/mediatek/clk-mtk.h | 12 + 38 files changed, 472 insertions(+), 1596 deletions(-) -- 2.55.0
