Hi Lee

The PHC driver already existed in the current tree as drivers/ptp/ptp_clockmatrix.c and
ptp_idt82p33.c

Right now, they act as i2c driver. I plan to change them as a normal platform device driver
after this MFD change kicked in

That is why I would prefer the name "phc" instead of "clock" since the driver is not a normal clk driver
under drivers/clk but a ptp clock driver. And down the road, we will have our real clock driver and I wanna
reserve the name "clock" for the real clock driver.

Thanks
