Patch Set #12, Line 156: ASYNC_MODE | DMAACK_EN |
These two flags are new here. […]
If AP_DMA and I2C use different source clocks, need enbale ASYNC_MODE and DMAACK_EN so that hardware will synchronize signals between AP_DMA and I2C.
New ICs use different source clocks between AP_DMA and I2C.

Patch Set #12, Line 83: static inline void i2c_dma_reset(struct mt_i2c_dma_regs *dma_regs)
Unused now?
It will be removed to src/soc/mediatek/common/i2c.c
