X-Git-Tag: firefly_0821_release~9833^2~3052^2~117^2~47 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c6a6e6e203ee9a34fa53f773272f21d48b4e3454;p=firefly-linux-kernel-4.4.55.git ARM: OMAP4: PM: OMAP4 essential basic initialisations. Some of the OMAP4 specific chip level initialisations are taken care of.
