Consider the following dump stack :
do_raw_spin_lock+0xf0
_raw_spin_lock_irqsave+0x80
mmc_request_done+0x48
sdhci_irq+0x954
__handle_irq_event_percpu+0x9c
handle_irq_event+0x60
handle_fasteoi_irq+0x140
__handle_domain_irq+0xc0
gic_handle_irq+0xcc
el1_irq+0x108
ktime_get+0xc0
mmc_cqe_clk_scaling_stop_busy+0x58
mmc_blk_cqe_complete_rq+0x138
mmc_blk_mq_complete+0x24
blk_done_softirq+0xe0
Here mmc_cqe_clk_scaling_stop_busy is being called from the soft irq
context and it acquires the clock_scaling lock.
Before it could unlock, a H/W irq gets triggered on the same core which
switches the context and starts execution but since lock is already held
in the softirq context, irq context ends up waiting for the same lock,
leading to a deadlock.
Use spin_lock_irqsave to avoid above explained deadlock.

When PVM lend an IRQ, a notification is given to SVM. Later SVM can
accept the IRQ that is lend by PVM. If the SVM do not accept an IRQ,
PVM can reclaim it back and lend again to SVM. This scenario is not
handled correctly and notification for lend from PVM to SVM is not
happening. Do an extra check in the callback handler whether previous
lend succeeded or not.

The proxy consumer driver currently only supports proxy
probing for platform bus. However, there's a need to
proxy-probe coresight devices, which falls under ABMA bus.
Hence, extend the driver to support proxy probing for
"struct amba_driver" and add coresight-etm ids to the list.

The ufs_reset pin is expected to be wired to the reset pin of the
primary UFS memory but is pretty much just a general purpose output pin.
Reorder the pins and expose it as gpio 204, so that the UFS driver can
toggle it.

The votes for power resources can only be removed if there are no
outstanding TLB invalidation operations. This is true when the
downstream io-pgtable-arm optimizations are in use, as the code that
unmaps the memory from the IOMMU page tables ensures that all TLB
operations are complete before returning.
However, the upstream io-pgtable-arm implementation allows for a TLB
invalidation to be in progress when control is returned back to
arm_smmu_unmap(), at which point the votes for the power resources
will be removed. In cases where the GPU is in slumber, the GPU block
and GPU SMMU get powered down when the SMMU driver removes its votes.
This causes problems where unmapping buffers takes a long time.
For scenarios where it is not feasible to guarantee that TLB
invalidations have completed when control is returned to the
arm_smmu_unmap() function, leave the votes for power resources in place,
and rely on the subsequent sync operation to remove the votes.

In an ONFI compliant devices, the flash parameters are calculated
by reading the onfi parameter page of the device.
Existing flash density is calculated based on a single logical
unit(LUN). This shows wrong density information on Multi LUN flashes.
So, always use number of LUNS value in flash density calculations.

Commit 3a1bd738ef ("dma-mapping-fast: Do not clobber existing atomic
pool") included the genalloc.h header file in the dma-mapping.h header
file.
Including genalloc.h in dma-mapping.h expands the definition of the
gen_pool structure for all files that include dma-mapping.h.
This can cause a different CRC value to be generated for an exported
function symbol, if the function parameters or any of their descendant
members contain genpool structures, as the genpool structures may have
been previously forward declared, but now they are fully defined.
Remove the inclusion of genalloc.h in dma-mapping.h to fix this.

The haptics module supports writing FIFO samples using 4-byte burst
mode as well as 1-byte mode. During FIFO refilling, if a 1-byte write
was used, then the hardware would fill zeros automatically after that
to keep the FIFO data 4-byte aligned. When this happened in the middle
of playing, the hardware inserted 0 values would cause spurs on the
haptics output. To fix this, only use 4-byte burst writes during FIFO
refilling until the end of the play.
