This serial of patches are adding support of mt2701/mt2712. there are many changes and HW improvement between mt8173 and mt2701/mt2712, below is a list of these changes: 1. enlarge CLKDIV bits from 8 to 12 2. remove the PAD_TUNE register and add a new PAD_TUNE0 register 3. add data sync and async fifo feature 4. add busy_check feature 5. add stop_clk fix 6. add enhance_rx support 7. add a seperate CG of source clock mt2712 supports full of these features, mt2701 supports part of it, and add a "mediatek,latch-ck" to work-around as it do not support stop-clk fix. Note: As Pinctrl/CCF are not ready now, so that current patches do not include DTS part.
