From 124294ff468fb3e2767473f2e317cd0ffa7eff90 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Mon, 6 Mar 2023 15:05:36 +0100 Subject: [PATCH] clk: mediatek: mt8192: Move apmixedsys clock driver to its own file This is the last man standing in clk-mt8192.c that won't allow us to use the module_platform_driver() macro, and for *no* good reason. Move it to clk-mt8192-apmixedsys.c and while at it, also add a .remove() callback for it. Also, since the need for "clk-mt8192-simple" and "clk-mt8192" was just due to them being in the same file and probing different clocks, and since now there's just one platform_driver struct per file, it seemed natural to rename the `-simple` variant to just "clk-mt8192".
