From 13032709e2328553970f0002df5edce6aac69425 Mon Sep 17 00:00:00 2001 From: Matthias Brugger Date: Wed, 25 Mar 2020 18:31:21 +0100 Subject: clk / soc: mediatek: Move mt8173 MMSYS to platform driver There is no strong reason for this to use CLK_OF_DECLARE instead of being a platform driver. Plus, MMSYS provides clocks but also a shared register space for the mediatek-drm and the mediatek-mdp driver. So move the MMSYS clocks to a new platform driver and also create a new MMSYS platform driver in drivers/soc/mediatek that instantiates the clock driver.
