Without this series as well OMAP4 ES1.0 is not booting for me. When I disable CONFIG_PM + WATCHDOG fix, it booted ok.

The omap4_mpuss_init() fails on ES1.0 and hence the CPUidle init is skipped in that case. Just to further check, I pulled the latest omap-for-linus branch and merged Paul's pull-request into it. Then applied OMAP4 PM series and I got a boot crash, a different one. This was again related to clock-domain initialization and static deps. I fixed this issue by avoiding omap4_pm_init() code running on ES1.0. With this boot on ES1.0 works fine now with OMAP4 PM series. Posted the patch for the same. https://patchwork.kernel.org/patch/628231/ The rebased series against Latest 'omap-for-linus + Paul's pull-request' have pushed to below branch. git://dev.omapzoom.org/pub/scm/santosh/kernel-omap4-base.git omap4_pm_for-next_v3 Regards, Santosh -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
