Subject: [PATCH 1/2] ARM: OMAP4: PM: Only do static dependency configuration in omap4_init_static_deps
Date: Tue, 21 Oct 2014 15:22:28 -0500 [thread overview]
Message-ID: <1413922949-22300-2-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1413922949-22300-1-git-send-email-nm@ti.com>
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.
Fixes: 705814b5ea6f ("ARM: OMAP4+: PM: Consolidate OMAP4 PM code to re-use it for OMAP5")
