Subject: RE: [RFC v1] clk: Add debugfs nodes for
 enable/disable/set-rate/set-parent

Hey

The prime motive for clk_set_rate is to set new rate for a clock, since the 'clk_rate' currently available, allows only reading.
To provide reading rate from 'clk_set_rate' is just additional feature.

Pankaj
