Remove microchip,sam9x60-spi compatible from the list as the driver used
has the compatible atmel,at91rm9200-spi and sam9x60 devices also use the
same compatible as fallback. So removing the microchip,sam9x60-spi
compatible from the list since it is not needed.

Current behavior is that spi-mem operations do not increment statistics,
neither per-controller nor per-device, if ->exec_op() is used. For
operations that do NOT use ->exec_op(), stats are increased as the
usual spi_sync() is called.
The newly implemented spi_mem_add_op_stats() function is strongly
inspired by spi_statistics_add_transfer_stats(); locking logic and
l2len computation comes from there.
Statistics that are being filled: bytes{,_rx,_tx}, messages, transfers,
errors, timedout, transfer_bytes_histo_*.
Note about messages & transfers counters: in the fallback to spi_sync()
case, there are from 1 to 4 transfers per message. We only register one
big transfer in the ->exec_op() case as that is closer to reality.
This patch is NOT touching:
- spi_async, spi_sync, spi_sync_immediate: those counters describe
precise function calls, incrementing them would be lying. I believe
comparing the messages counter to spi_async+spi_sync is a good way
to detect ->exec_op() calls, but I might be missing edge cases
knowledge.
- transfers_split_maxsize: splitting cannot happen if ->exec_op() is
provided.

In the AXI SPI Engine driver, compiling the message is an expensive
operation. Previously, it was done per message transfer in the
prepare_message hook. This patch moves the message compile to the
optimize_message hook so that it is only done once per message in
cases where the peripheral driver calls spi_optimize_message().
This can be a significant performance improvement for some peripherals.
For example, the ad7380 driver saw a 13% improvement in throughput
when using the AXI SPI Engine driver with this patch.
Since we now need two message states, one for the optimization stage
that doesn't change for the lifetime of the message and one that is
reset on each transfer for managing the current transfer state, the old
msg->state is split into msg->opt_state and spi_engine->msg_state. The
latter is included in the driver struct now since there is only one
current message at a time that can ever use it and it is in a hot path
so avoiding allocating a new one on each message transfer saves a few
cpu cycles and lets us get rid of the prepare_message callback.

Since splitting transfers was moved to spi_optimize_message() in the
core SPI code, we now need to use the optimize_message callback in the
STM32 SPI driver to ensure that the operation is only performed once
when spi_optimize_message() is used by peripheral drivers explicitly.

Splitting transfers is an expensive operation so we can potentially
optimize it by doing it only once per optimization of the message
instead of repeating each time the message is transferred.
The transfer splitting functions are currently the only user of
spi_res_alloc() so spi_res_release() can be safely moved at this time
from spi_finalize_current_message() to spi_unoptimize_message().
The doc comments of the public functions for splitting transfers are
also updated so that callers will know when it is safe to call them
to ensure proper resource management.

This adds a new spi_optimize_message() function that can be used to
optimize SPI messages that are used more than once. Peripheral drivers
that use the same message multiple times can use this API to perform SPI
message validation and controller-specific optimizations once and then
reuse the message while avoiding the overhead of revalidating the
message on each spi_(a)sync() call.
Internally, the SPI core will also call this function for each message
if the peripheral driver did not explicitly call it. This is done to so
that controller drivers don't have to have multiple code paths for
optimized and non-optimized messages.
A hook is provided for controller drivers to perform controller-specific
optimizations.

Set the ->num_chipselect field in struct cqspi_st and struct

Change the maximum chip-select count in cadence-qspi to 4 instead of 16.
The value gets used as default ->num_chipselect when the num-cs DT
property isn't received from devicetree. It also determines the
cqspi->f_pdata array size.
Hardware only supports values up to 4; see cqspi_chipselect() that sets
CS using a one-bit-per-CS 4-bit register field.
Add a static_assert() call as a defensive measure to ensure we stay
under the SPI subsystem limit. It got set to 4 when introduced in
4d8ff6b0991d ("spi: Add multi-cs memories support in SPI core") and
later increased to 16 in 2f8c7c3715f2 ("spi: Raise limit on number of

In PCI1xxxx C0, support for DMA in PCIe endpoint is added
to enhance the SPI performance. With this support, the
performance is improved from 6Mbps to 17Mbps with 20Mhz clock.
- DMA Supports two Channels, 0 and 1
- SPI Instance 0 uses chan 0 and SPI Instance 1 uses chan 1
- DMA can be used only if SPI is mapped to PF0 in the multi
function endpoint and the MSI interrupt is supported
- MSI interrupt of one of the SPI instance is assigned to the DMA
and both channels 0 and 1 share the same irq, the MSI address and
MSI Data of the irq is obtained and stored in DMA registers to
generate interrupt
