The wrapper controller has only clock parts, or are the clock register mapped
into the i2c wrapper block. In that case we might want to probe the clock driver
through the i2c wrapper driver.

Yes, the clock registers are mapped into partial of the i2c wrapper
block.
AFAIK, the i2c wrapper works with the i2c
driver(i2c/busses/i2c-mt65xx.c) but not a new driver.
So do you still suggest us to probe the clock driver through the i2c
driver(i2c/busses/i2c-mt65xx.c) just like the mtk-mm driver?
