If anyone has any objections, please let me know. =============== commit 9008d83fe9dc2e0f19b8ba17a423b3759d8e0fd7 upstream. Commit 705814b5ea6f ("ARM: OMAP4+: PM: Consolidate OMAP4 PM code to re-use it for OMAP5") Moved logic generic for OMAP5+ as part of the init routine by introducing omap4_pm_init. However, the patch left the powerdomain initial setup, an unused omap4430 es1.0 check and a spurious log "Power Management for TI OMAP4." in the original code. Remove the duplicate code which is already present in omap4_pm_init from omap4_init_static_deps. As part of this change, also move the u-boot version print out of the static dependency function to the omap4_pm_init function.
