This patch adds the bus device-tree node of INT (internal) block
to enable the bus frequency scaling. The following sub-blocks share
the VDD_INT power source:
- LEFTBUS (parent device)
- RIGHTBUS
- PERIL
- LCD0
- FSYS
- MCUISP / ISP
- MFC
The LEFTBUS is parent device with devfreq ondemand governor
and the rest devices has the dependency on LEFTBUS bus.

I pointed this previously. If you wish to leave the sentence in such form then "rest of" and "have" not "has".

If you wish to leave the sentence in such > form then "rest of" and "have" not "has". It is my mistake. I'll modify it as following your comment: - "and the rest of devices depend on the LEFTBUS device."
