spi: spi-fsl-qspi: Add ls2080a compatibility string to bindings
There are 2 version of QSPI-IP, according to which controller registers sets
can be big endian or little endian.There are some other minor changes like
RX fifo depth etc.

The big endian version uses driver compatible "fsl,ls1021a-qspi" and
little endian version uses driver compatible "fsl,ls2080a-qspi"

spi: spi-fsl-dspi: Move dspi_interrupt above dspi_transfer_one_message
The two functions are loosely coupled through dspi->waitq, but
logically, dspi_transfer_one_message depends on dspi_interrupt in order
to complete. Move its definition above it so the I/O functions are
grouped closer together.

spi: Remove dev_err() usage after platform_get_irq()
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

The SPI thingies request FIFO-99 by default, reduce this to FIFO-50.

FIFO-99 is the very highest priority available to SCHED_FIFO and
it not a suitable default; it would indicate the SPI work is the

Now Spreadtrum ADI controller supplies multiple master accessing channel

To keep backward compatibility, we should change the hardware spinlock

8cf6650421 iommu/amd: fix a crash in iova_magazine_free_pfns
The commit b3aa14f022 ("iommu: remove the mapping_error dma_map_ops
method") incorrectly changed the checking from dma_ops_alloc_iova() in
map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
never return DMA_MAPPING_ERROR on failure but 0, so the error handling
is all wrong.

618381f09c hexagon: switch to generic version of pte allocation
The hexagon implementation pte_alloc_one(), pte_alloc_one_kernel(),
pte_free_kernel() and pte_free() is identical to the generic except of
lack of __GFP_ACCOUNT for the user PTEs allocation.

Switch hexagon to use generic version of these functions.

7d9ef7f37d dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodes
Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.
