From e09eb9d24053a450cdcb465c40e9982b4a808941 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Fri, 20 Jan 2023 10:20:49 +0100 Subject: clk: mediatek: clk-mt8192: Migrate topckgen to mtk_clk_simple_probe() Since the common simple probe function for MediaTek clock drivers can now register the MFG MUX notifier, it's possible to migrate MT8192's topckgen to that, allowing for some code size reduction.
