Add extcon listeners for EXTCON_USB and EXTCON_USB_HOST cable
types to be notified of VBUS and ID notifications respectively.
Upon notification this will start the controller in either
peripheral or host mode.
This replaces the handling previously done in the power_supply
set_property() callback for PROP_PRESENT and PROP_USB_OTG. The
usb_psy will be removed in its entirety following this patch.

Since msmcobalt RUMI uses QRBTC-V2 UFS PHY, there are a few limitations
that must be applied in order to be able to initialize UFS:
1. UFS should remain in PWM-G1 1-Lane and never change its gear, as other
gears are not stable
2. hibern8 enter/exit should be bypassed
3. we should avoid any power change (as in runtime suspend/resume)
Add "qcom,disable-lpm" property to facilitate disabling of these.

To implement slave side protection, programming of
global registers as well as secure context bank
registers is handed over to TZ. Now, instead of
dynamically allocating context banks, TZ allocates
CBs once in pre defined static manner during boot
and this allocation is maintained throughout the
life of system.
Add an option to enable use of this pre-defined
context bank allocation. We would be reading
through SMR and S2CR registers at run time
to identify CB allocated for a particular sid.

With modification in scheduler, governor now gets predicted
instantaneous demand waiting to run in addition to demand from
previous window for each CPU. Make use of this information since
prediction from scheduler could be more accurate than just looking at
past few windows.
Governor calculates two frequencies during each sampling period: one based
on demand in previous sampling period (f_prev), and the other based on
prediction provided by scheduler (f_pred). Max of both will be selected
as final frequency. Hispeed related logic, including both frequency
selection and delay is ignored when prediction is enabled. If only
f_pred but not f_prev picked policy->max, max_freq_hysteresis period is
not started/extended. This is to reduce power cost of mis-prediction
if it happens.
One use case prediction could dramatically help is when a heavy task
wakes up after sleeping for a long time. With prediction, governor
could ramp up to frequency the task needs much faster than before.
To enable prediction, echo 1 to enable_prediction file in
cpufreq interactive sysfs directory.

Biasing sync wakee task towards waker CPU's cluster makes sense when the
waker's demand is high enough so the wakee also can take advantage
of high CPU frequency voted because of waker's load. Placing sync wakee
on the low demand waker's CPU can lead placement imbalance which can
lead unnecessary migration.
Introduce a new tunable "sched_big_waker_task_load" that defines the big
waker so scheduler avoid wakee on waker's cluster bias when the waker's
load is below the tunable.

If sync wakee task's demand is small it's worth to place the wakee task
on waker's cluster for better performance in the sense that waker and
wakee are corelated so the wakee should take advantage of waker cluster's
frequency which is voted by the waker along with cache locality benefit.
While biasing towards the waker's cluster we want to avoid the waker CPU
as much as possible as placing the wakee on the waker's CPU can make the
waker got preempted and migrated by load balancer.
Introduce a new tunable 'sched_small_wakee_task_load' that differentiates
eligible small wakee task and place the small wakee tasks on the waker's
cluster.

The frequency based inter cluster load balance restrictions are not
reliable as frequency does not provide a good estimate of the CPU's
current load. Replace them with the spill_load and spill_nr_run
based checks.
The higher capacity cluster is restricted from pulling the tasks from
the lower capacity cluster unless all of the lower capacity CPUs are
above spill. This behavior can be controlled by a sysctl tunable and
it is disabled by default (i.e. no load balance restrictions).
