X-Git-Tag: firefly_0821_release~9833^2~3961^2~69^2^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8e431edb60ef175e6aa986e8260b23cc267a13fb;p=firefly-linux-kernel-4.4.55.git

OMAP3: PM: CPUidle: Start C-state definitions from base 0

The current definition of C-states starts from base 1.
Whereas, the cpuidle driver uses base 0. This patch
eliminates need for explicit mapping (add/ sbutract)
due to different base values.
