OK, I'll modify it.

How about:
"and the rest of devices depend on the LEFTBUS device."
?

[PATCH v2 17/19] ARM: dts: Add support of bus frequency using VDD_INT for exynos3250-rinato

2015-12-08 Thread Chanwoo Choi 
This patch adds the bus device-tree node of INT (internal) block
to enable the bus frequency. 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.
