From: AngeloGioacchino Del Regno Date: Mon, 6 Mar 2023 14:05:17 +0000 (+0100) Subject: clk: mediatek: mt8516: Move apmixedsys clock driver to its own file X-Git-Tag: v6.6.7~2872^2~7^2~49 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f419069ad864bdb6a9ba5a38ea01224187376d6e;p=platform%2Fkernel%2Flinux-starfive.git clk: mediatek: mt8516: Move apmixedsys clock driver to its own file In preparation for migrating mt8516 clocks to the common simple probe mechanism, convert the apmixedsys to be a separated platform driver and move it to clk-mt8516-apmixedsys.c. While at it, also fix some indentation issues. During the conversion, error handling was added to the apmixedsys probe function.
