Hi,
I am having some hangs using origin/pm branch. SDPs used to test, same
behaviour:
SDP3430 PROCESSOR BD, ES2.0
SDP3430 PROCESSOR BD III, OMAP3430 ES3.0 EMU(MT), TWL5030 ES1.0
The commit taken is latest:
commit 9d76f46e79302058464b569dbad9af8c594dbe53
author Roger Quadros <ext-roger.quadros@xxxxxxxxx>
PM: OMAP: Fix build with CONFIG_OMAP_PM_NONE set
If default configuration is used (omap_3430sdp_defconfig) then a
kernel panic will occur:
<7>Switched to high resolution mode on CPU 0
<6>musb_hdrc: version 6.0, musb-dma, otg (peripheral+host), debug=0

If USB is disabled then a hang now will be present in Power Management

To avoid this last hang going back to the previous commit is needed,
after this, the boot is Ok
commit 90c3bdfb394ff2ddd87a72defb49c2f2456dd621
Author: Rajendra Nayak <rnayak@xxxxxx>
OMAP3 clock: Update cpufreq driver
If minimal defconfig (omap_3430sdp_min_defconfig) is used, boot will be ok.
Has anyone faced same issue?
Best Regards
Abraham
