Hence most drivers can be reused and not much is missing the get also this SoC working on mainline Linux. Start with a cleaned-up version of the clock drivers, based on what can also be found in MediaTek's SDK[1]. Upon request of AngeloGioacchino Del Regno this series has been rebased and adapted to be applied on top of the pending series "MediaTek clocks cleanups and improvements"[2] The complete tree used for testing (with still some to-be-cleaned-up changes, esp. for the Ethernet driver) can be found on Github[3].
