This function can be used to initiate a scatter-gather DMA transfer,
where the address and size of each segment is located in one entry of
the dma_vec array.

The major difference with dmaengine_prep_slave_sg() is that it supports
specifying the lengths of each DMA transfer; as trying to override the
length of the transfer with dmaengine_prep_slave_sg() is a very tedious
process. The introduction of a new API function is also justified by the
fact that scatterlists are on their way out.

Note that dmaengine_prep_interleaved_dma() is not helpful either in that
case, as it assumes that the address of each segment will be higher than
the one of the previous segment, which we just cannot guarantee in case
of a scatter-gather transfer.

The calls write_lock/unlock_irq() disables and re-enables the IRQs.
Calling spin_lock_irqsave() and spin_lock_restore() when the IRQs are
already disabled doesn't do anything and just makes the code confusing.

Fix the issue where MEM_TO_MEM fail on i.MX8QM due to the requirement
that both source and destination addresses need pass through the IOMMU.
Typically, peripheral FIFO addresses bypass the IOMMU, necessitating
only one of the source or destination to go through it.

Set "is_remote" to true to ensure both source and destination
addresses pass through the IOMMU.

iMX8 Spec define "Local" and "Remote" bus as below.
Local bus: bypass IOMMU to directly access other peripheral register,
such as FIFO.
Remote bus: go through IOMMU to access system memory.

The test fail log as follow:

The edma feature individual IRQs for each DMA channel at some devices.
Given the presence of numerous eDMA instances, each with multiple channels,
IRQ request during probe results in an extensive list at /proc/interrupts.
However, a significant portion of these channels remains unused by the
system.

Request irq only when a DMA client driver requests a DMA channel.

On STM32 DMA3, channels can be reserved, so they are non available for
Linux. This non-availability creates a mismatch between dma_chan id and
DMA3 channel id.

Use dma_async_device_channel_register() to register the channels
after controller registration and change the default channel name, so that
it can match the name in the Reference Manual and ease requesting a channel
thanks to its name.

Implement own device_tx_status ops to compute the residue with a finer
granularity, up to bytes.
STM32 DMA3 has a bitfield, BNDT, in CxTR1 register which reflects the
number of bytes read from the source.
It also has a bitfield, FIFOL, in CxSR register which reflects the FIFO
level in units of programmed destination data width.
The channel is briefly suspended to get a coherent snapshot of registers.
It is possible to correct the fifo level when packing/unpacking is enabled
with destination increment.

STM32 DMA3 driver supports the 3 hardware configurations of the STM32 DMA3
controller:
- LPDMA (Low Power): 4 channels, no FIFO
- GPDMA (General Purpose): 16 channels, FIFO from 8 to 32 bytes
- HPDMA (High Performance): 16 channels, FIFO from 8 to 256 bytes
Hardware configuration of the channels is retrieved from the hardware
configuration registers.

The client can specify its channel requirements through device tree.
STM32 DMA3 channels can be individually reserved either because they are
secure, or dedicated to another CPU.
Indeed, channels availability depends on Resource Isolation Framework
(RIF) configuration. RIF grants access to buses with Compartment ID (CID)
filtering, secure and privilege level. It also assigns DMA channels to one
or several processors.
DMA channels used by Linux should be CID-filtered and statically assigned
to CID1 or shared with other CPUs but using semaphore. In case CID
filtering is not configured, dma-channel-mask property can be used to
specify available DMA channels to the kernel, otherwise such channels
will be marked as reserved and can't be used by Linux.

STM32 DMA3 is a new STM32 DMA controller, not a new version of an existing
one.
stm32-dma is not considered for reuse because register layout is completely
different and doesn't rely on descriptors mechanism.
stm32-mdma is based on descriptors mechanism but there are significant
differences in register layout and descriptors structure.

The STM32 DMA3 is a Direct Memory Access controller with different features
depending on its hardware configuration.
The channels have not the same capabilities, some have a larger FIFO, so
their performance is higher.
This patch describes STM32 DMA3 bindings, used to select a channel that
fits client requirements, and to pre-configure the channel depending on
the client needs.
