linux/drivers/clk/mediatek/clk-mt7988-topckgen.c
Sam Shih 4b4719437d clk: mediatek: add drivers for MT7988 SoC 
Add APMIXED, ETH, INFRACFG and TOPCKGEN clock drivers which are
typical MediaTek designs.

Also add driver for XFIPLL clock generating the 156.25MHz clock for
the XFI SerDes. It needs an undocumented software workaround and has
an unknown internal design.
