This series adds support for the main clock and reset controllers on the Mediatek MT6735 SoC: - apmixedsys (global PLLs) - topckgen (global divisors and muxes) - infracfg (gates and resets for internal components) - pericfg (gates and resets for peripherals) MT6735 has other more specialized clock controllers, support for which is not included in this series: - imgsys (camera) - mmsys (display) - vdecsys (video decoder) - audsys (audio) Tested on a Samsung Galaxy Grand Prime+ "grandpplte" with MT6737T, a slight variant of MT6735 with no known differences in the clock controllers. Dependencies: - clk: mediatek: Move to struct clk_hw provider APIs (series) https://patchwork.kernel.org/project/linux-mediatek/cover/20220510104804.544597-1-wenst@xxxxxxxxxxxx/ - Cleanup MediaTek clk reset drivers and support MT8192/MT8195 (series) https://patchwork.kernel.org/project/linux-mediatek/cover/20220503093856.22250-1-rex-bc.chen@xxxxxxxxxxxx/ - Export required symbols to compile clk drivers as module (single patch) https://patchwork.kernel.org/project/linux-mediatek/patch/20220518111652.223727-7-angelogioacchino.delregno@xxxxxxxxxxxxx/ - clk: mediatek: Improvements to simple probe/remove and reset controller unregistration https://patchwork.kernel.org/project/linux-clk/cover/20220519134728.456643-1-y.oudjana@xxxxxxxxxxxxxx/ Above are dependencies for patch 4/4 only; DT bindings don't need them. Changes since v1: - Rebase on some pending patches (listed as dependencies above). - Move common clock improvemenets to a separate series (last dependency listed above). - Use mtk_clk_simple_probe/remove after making them support several clock types in said series. - Combine all 4 drivers into one patch, and use one Kconfig symbol for all following a conversation seen on a different series[1]. - Correct APLL2 registers in apmixedsys driver (were offset backwards by 0x4). - Make irtx clock name lower case to match the other clocks.
