Start confirming to arm,idle-state compatible definition. In addition to
being compliant, this allows us to use the new API to setup the PSCI
cluster state ids for the CPU, before entering the idle state.
Let's do the following:
- Rename enter/exit latency, residency, label properties
- In addition to qcom,psci-cpu-mode specify
arm,psci-suspend-param.
- Update copyright

This is a snapshot of the Sleep driver and related functionality as of
'commit b252df6e0200 ("cpuidle: lpm-levels: log enabled regulators
before entering suspend")' on msm-4.19 branch.
Updates:
- Remove event timers
- Remove per-cpu PM QoS
- Remove rpm stats (Use new soc_sleep_stats driver instead)
- Update __arch_counter_get_cntvct (new)
- Update to get next wakeup from cpuidle device
- Remove pending_ipi and is_IPI_pending() (defined in smp.c)
- Update copyright
- Update Kconfig menu items
- Update hotplug enum to use the already upstreamed
- ifdef's around scheduler functions that are not upstreamed

For NCM gadget function, net device structure opts->net
will be freed when NCM unbind, but user space related
device node doesn't know it, will access net structre
without checking it exist or not, leading to potential
use-after-free.
Fix this by adding check gadget function bind or not.

It may be useful to debug how much time is spent in the
DWC3 hard IRQ context. Add low-overhead statistics counters
which keep a histogram of the last 10 interrupts' time of
occurrence, time spent, and number of events read (which will
get processed in the bottom half handler).

This change adds debug support to log all received different
events with endpoint0, other endpoints and gadget events. It
tracks these events per endpoint and displays the same.
For each of the endpoint event counters, add the rate (in Hz)
at which it occurs in order to better analyze performance and
aid in optimization.
How to use:
- Mount debugfs
- To see received all dwc3 events/interrupts
cat /sys/kernel/debug/<base_address>.dwc3/int_events
- To clear all received dwc3 events/interrupts
echo 0 > /sys/kernel/debug/<base_address>.dwc3/int_events

This change creates separate debug buffer with each DWC instance and
provides debug API to log different important events using IPC
logging framework.

XHCI allows interrupt moderation using imod_interval at 250ns
increments. Add DT parameter to specify this imod_value for
targets mainly with single CPU to reduce CPU interrupt loads.
This allows better balance between CPU usage and performance.

Default 0 value for IP_GAP_ADD_ON field of DWC3_GUCTL1
register is causing failure of EL_23 test. This value
corresponds to inter-packet gap of 182.163 ns. Increase
the value to 1 which corresponds to 199.794 ns. This
improves margin required to pass the test.

Ensure that shrinkers are given the option to completely drop
their caches even when their caches are smaller than the batch size.
This change helps improve memory headroom by ensuring that under
significant memory pressure shrinkers can drop all of their caches.
This change only attempts to more aggressively call the shrinkers
during background memory reclaim, inorder to avoid hurting the
perforamnce of direct memory reclaim.
