From 3b5bc4691f13e19d72f1fc5312ce5ee89ef51748 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Fri, 20 Jan 2023 10:20:44 +0100 Subject: [PATCH] clk: mediatek: clk-mt8192: Move CLK_TOP_CSW_F26M_D2 in top_divs This driver is registered early in clk_mt8192_top_init_early() and then again in clk_mt8192_top_probe(): the difference between the two is that the early one is probed with CLK_OF_DECLARE_DRIVER and the latter is regularly probed as a platform_driver. Knowing that it is not necessary for this platform to register the TOP_CSW_F26M_D2 clock that early, move it to top_divs and register it with the others during platform_driver probe for topckgen; While at it, since the only reason why the early probe existed was to register that clock, remove that entirely - leaving this driver to use only platform_driver.
