Messages in this thread Patch in this message | | | From | AngeloGioacchino Del Regno <> | Subject | [PATCH v1 12/45] clk: mediatek: mt8365: Convert to mtk_clk_simple_{probe,remove}() | Date | Mon, 6 Feb 2023 16:28:55 +0100 |
| |
Change the custom mt8365_simple_gate to be mtk_gate clocks and audio clocks to be composites to be consistent with all of the other MediaTek clock drivers, allowing to convert this entire driver to use the common mtk_clk_simple_probe() mechanism that also allows building this driver as module.
While at it, also perform some macro compression cleanups and switch to use module_platform_driver().
