| |
The MediaTek AI Processing Unit (APU) is a proprietary hardware in the SoC to support AI operations. The series is to create apusys in the SoC folder for developing the related drivers. Add the apu clocks, basic apu nodes and the power domain to provide the power controller of APU subsystem.
This series is based on MT8192 power domain[1], PWRAP[2] and PMIC MT6359[3] patches. [1] https://patchwork.kernel.org/patch/12456165 [2] https://patchwork.kernel.org/patch/12134935 [3] https://patchwork.kernel.org/patch/12140237
Change notes: v3->v4: 1) Rebase to 5.16-rc1 2) Update mtk-apu-pm driver to be a module or a buildin driver. 3) Fix coding defects and typo in mtk-apu-pm.c and update copyright in dt-bindins. 4) Split the mt8192 EVB device tree "mt8192-evb.dts" to a new patch file in the series.
v2->v3: 1) Rebase to 5.15-rc1 2) remove the apu-mbox registers from syscon. 3) update mtk-apu-pm to fix clock flow and move power status bit into platform data to support different hardware settings.
v1->v2: 1) update expression "s/_/-/" in dt-bindings documents. 2) drop apu power domain header file for mt8192.
