There are high chances for hrtimer_interrupt() interrupt on
one of the core and other core executing sys_reboot simultaneously.
In such a situation we could see ipi_cpu_stop() marking a cpu
as 'offline' but hrtimer_wakeup() can schedule a task on
offline core, resulting BUG_ON in smp_send_reschedule().
In fact that the CPU is not really offline but ipi_cpu_stop()
is marking it as offline.

check_preempt_curr()
smp_send_reschedule()
BUG_ON(cpu_is_offline(1));
This is easily reproducible in device continuous reboot testing.
Since the CPU is not really offline and hasn't gone through the
proper steps to be marked as such, let's mark the CPU as inactive.

instances on the CDP_AU board. Add the PM8994 GPIO/MPP
configurations and expose them as usb_vbus_vreg,
usb_otg_switch and usb2_otg_switch regulators that can be

Also fix up the &usb3 node. Due to commit c51ea2bbbce87
("ARM: dts: msm: Add GIC ITS extensions for 8996") changing
the size of address-cells for the &intc node, the interrupt-map
property needs to be updated to the new format. Also update
the correct IRQ numbers and add the missing ss_phy_irq to
sync up with the msm8996 SOC DT definition. Finally, remove
the unused vdda supply entries as well.

A small fraction of MSM8996v3 parts with CPR revision 0 to 5 may
not operate properly at very low VDD_APCC voltages. Therefore
increase the VDD_APCC CPR floor voltage for these parts to 625 mV
in order to guarantee stable operation.
Also change the maximum CPR floor to ceiling voltage range from
80 mV to 50 mV for all MinSVS and LowSVS corners in order to
ensure stable operation.

Initialize PMCOBALT regulators SMPS 7 and LDO 5 to use HW_EN0 pin
control to force high power mode. Whenever HW_EN0 is driven high these
regulators will be forced into high power mode.
HW_EN0 is driven high whenever WLAN is transmitting or receiving, thereby
reducing power when it is not active.
Initialize PMCOBALT regulators SMPS 3 and SMPS 5 to use HW_EN2 pin
control to force high power mode. Whenever HW_EN2 is driven high these
regulators will be forced into high power mode.
Add pin control regulator devices for PMCOBALT regulators LDO 7, LDO
17, and LDO 25. When any of these pin control regulators are enabled by
software their output will be physically enabled whenever HW_EN2 is driven
high. When disabled HW_EN2 is ignored.
HW_EN2 is driven high whenever BT is transmitting or receiving, thereby
reducing power when it is not active.

On a HMP system, scheduler needs to know efficiency factor
(instructions-per-cycle) for various cpus. This is so that scheduler
can estimate bandwidth consumption of tasks on each cpu, based on
their efficiency factor.
This patch defines arch_get_cpu_efficiency() API in ARM64
architecture. It depends on hard-coded "efficiency" factor for
various cpu types (available in 'table_efficiency' data structure) and
device-tree providing information on cpu-type for every cpu.
