From: Sean Wang <sean.wang@mediatek.com> For more readability and maintenance, all the clock related DT nodes for mt7622 SoC are grouped into a separate DT file. And currently mt7622-clock.dtsi only includes the fixed clock for uart0 and the oscillator which would be extended after MT7622 clock driver is introduced.
