Add support to report INPUT_SUSPEND state in case of slave charger
configuration. This is used by user-space to determine parallel
charger state.

Skip VMA_LOCKED vmas from being reclaimed. Not doing so results
in pages in unevictable lrus to be passed for reclaim which can
cause issues. In one such reported problem, the trylock_page in
shrink_page_list fails and reclaim path decides to keep the page
and hits VM_BUG_ON_PAGE since PageUnevictable is set.

For video mode panels, when secure display has ended and non-secure
layers are being committed, check if secure display is still enabled.
Ideally there should be a NULL commit before non-secure content starts,
to clean up the secure display. If this isn't the case, add code to
detect, validate, and return failure.

trigger_ssr_write directly accesses user buffer, which can lead
to crash. Copy user buffer to kernel memory before access.
Also, set initial value for ssr_trigger_val, and use kstrtoul
instead of sscanf, with proper checking of return code.

With ESR discharge timer retry, max having same value, ESR pulse
can fire frequently when battery FET is open past charge
termination. This frequent ESR pulses increase power consumption
when the device is idle.
Upon charge termination, change the ESR discharging timer retry
to 0 so that ESR pulse can fire less frequently saving power.
Add support for this through fg_esr_timer_config() based on end
of charge and sleep conditions.
Currently, retry/max for ESR charging and discharging timers are
configured with the same value specified through device tree.
Extend the device tree property to take in different retry/max
values for those timers.

The cycle counter read is a bit of an expensive operation and requires
locking across all CPUs in a cluster. Optimize this by returning the
same value if the delta between two reads is zero (so if two reads are
done in the same sched context) or if the last read was within a
specific time period prior to the current read.

We observe that while PR_SWAP is done from PD stack, the typeC
block could be running its tCC debounce timer. This causes the
driver to prematurely declare that the cable is removed.
Fix this by reducing the tCC debounce time to 20mS while in
PR_SWAP.

At a higher level, all objects are created with definite size i.e. 0 is
illegal. In forthcoming patches, this assumption is dependent upon in
the drm_mm range manager, i.e. trying to create a drm_mm node with size
0 will have undefined behaviour. Add a couple of WARNs upon creating the
drm_mm node to prevent later bugs.

we do not need to initialise the list node.

In addition to the last-in/first-out stack for accessing drm_mm nodes,
we occasionally and in the future often want to find a drm_mm_node by an
address. To do so efficiently we need to track the nodes in an interval
tree - lookups for a particular address will then be O(lg(N)), where N
is the number of nodes in the range manager as opposed to O(N).
Insertion however gains an extra O(lg(N)) step for all nodes
irrespective of whether the interval tree is in use. For future i915
patches, eliminating the linear walk is a significant improvement.
v2: Use generic interval-tree template for u64 and faster insertion.
