Unless I'm missing something, this patch appears to have still not been
picked up. It would be nice if it can go in for 3.18 so that we have
working USB on pandaboard again at least in that release.
Tony, would you mind carrying it as OMAP maintainer since we haven't
heard anything from Kishon

All the PHY configuration other than VBUS, ID GND and OTG SRP are removed
from twl6030. The phy configurations are taken care by the dedicated
usb2 phy driver. So twl6030 is made as comparator driver for VBUS and
ID detection.

This patch supports pmu irq routed from CTI, so
make pmu/perf working on OMAP4.
The idea is from Woodruff Richard in the disscussion
about Oprofile on Pandaboard / Omap4 on

On a linux-next kernel built for the Pandaboard, disabling
CONFIG_OMAP_32K_TIMER makes the kernel use the gptimer as the
clocksource, but this appears to be non-functional. Judging from the
all-zeros printk timings and the fact the sleep 1 hangs indefinitely,
it looks like the clocksource reads

Include sched.h to ensure sched_clock() has the notrace
annotation, and mark any functions it calls as notrace
too.
