write_seqcount_begin expects to be called from a non-preemptible
context to avoid preemption by a read section that can spin due
to an odd value. But the readers of vm_sequence never retries and
thus writers need not disable preemption. Use the non-lockdep
variant as lockdep checks are now in-built to write_seqcount_begin.

Add code to update the bound checks for sbl reg dumps to SRAM mem
range. Due to a firmware update, the sbl start address was moved
and the bound checks to dumps sbl reg failed. Update the bound
checks to SRAM mem range, so that any future update in firmware
would not impact SRAM dumps.

When system shuts down while there are work running on NPU,
NPUSS will be shut down without notifying kernel driver which
causes IPC commands timedout and triggers SSR handling.
This change is to detect this case and handle it properly
to avoid SSR.

The underlying arm-smmu hardware only supports mapping addresses
aligned to PAGE_SIZE. Thus the actual mapped region may be larger than
the range returned by iommu_map_sg():
[sg_dma_address(), sg_dma_address() + sg->length)
When unmapping, ensure the same alignment requirements are applied
in order to avoid leaking iova addresses.

This is snapshot of qpnp-adc-tm driver as of
msm-4.9 'commit 7e65e03259909 (Merge "msm: kgsl:
Deregister gpu address on memdesc_sg_virt failure")'.
Removed support for adc_tm_hc and hkadc_ldo as they
are not used for SPF targets. Removed IADC, VADC APIS,
structs and enums not needed for ADC_TM. VADC functions
required for sake of compilation have been retained,
which will be subsequently replaced with IIO functions
to suit msm-4.19.

Currently during nop desc send, we are setting
nop pending flag to false before queing desc,
due to which we are not able to queue nop desc
again if it fails for first time. Now setting
nop pending flag to false only if we successfully
queued nop desc.

Some graphics APIs want the ability to create and use timelines
with 64 bit sequence numbers to synchronize between threads.
Add support for timelines that can be created, signaled and managed from
user space. Timelines can also be signaled from a draw context command
stream via an auxiliary command and a wait can be added as a sync object
to any GPU command.

Currently driver calculating stale delay based on baud rate during
stop_rx sequencer. When BT started with lower baud rate like 2400
this logic will add around 130msecs of extra delay during BT INIT.
This change will remove logic for stale delay calculation
based on baud rate and add constant delay of 10msec to
wait for stale interrupt during stop_rx_sequencer.

Currently, the f_mtp driver marks the mtp_tx_req_len to 1M.
As a result, file transfer from device to host PC fails for
devices using ChipIdea controller since it does not allow request
length greater than 16k for IN Endpoint. Hence, to allow such
file transfers, limit Tx req length to 16k.
