clk: mediatek: Select all the MT8183 clocks by default 2021-02-09T07:47:04+00:00 Enric Balletbo i Serra enric.balletbo@collabora.com 2021-02-03T10:54:23+00:00 8c18e927b10d4c6abdfd5b0bb60603df5b9ac56e If MT8183 SoC support is enabled, almost all machines will use topckgen, apmixedsys, infracfg, mcucfg and subsystem clocks, so it feels wrong to require each one to select that symbols manually. Instead, enable it whenever COMMON_CLK_MT8183_* is disabled as a simplification. This would add few KB in the kernel image size but will make the life a bit easier to the users, anyway you'll need to probably enable all of them if you want to have proper support for that SoC.
