The bam_dma driver needs to know the number of channels and execution
environments (EEs) at probe time. If we are in full control of the BAM
controller this information can be obtained from the BAM identification
registers (BAM_REVISION/BAM_NUM_PIPES).
When the BAM is "controlled remotely" it is more complicated. The BAM
might not be on at probe time, so reading the registers could fail.
This is why the information must be added to the device tree in this
case, using "num-channels" and "qcom,num-ees".
However, there are also some BAM instances that are initialized by
something else but we still have a clock that allows to turn it on when
needed. This can be set up in the DT with "qcom,controlled-remotely"
and "clocks" and is already supported by the bam_dma driver. Examples
for this are the typical BLSP BAM instances on older SoCs, QPIC BAM
(for NAND) and the crypto BAM on some SoCs.
In this case, there is no need to read "num-channels" and
"qcom,num-ees" from the DT. The BAN can be turned on using the clock
so we can just read it from the BAM registers like in the normal case.
Check for the BAM clock earlier and skip reading "num-channels" and
"qcom,num-ees" if it is present to allow simplifying the DT description
a bit.

Add support for HDMA NATIVE, as long the IP design has set
the compatible register map parameter-HDMA_NATIVE,
which allows compatibility for native HDMA register configuration.
The HDMA Hyper-DMA IP is an enhancement of the eDMA embedded-DMA IP.
And the native HDMA registers are different from eDMA, so this patch
add support for HDMA NATIVE mode.
HDMA write and read channels operate independently to maximize
the performance of the HDMA read and write data transfer over
the link When you configure the HDMA with multiple read channels,
then it uses a round robin (RR) arbitration scheme to select
the next read channel to be serviced.The same applies when you
have multiple write channels.
The native HDMA driver also supports a maximum of 16 independent
channels (8 write + 8 read), which can run simultaneously.
Both SAR (Source Address Register) and DAR (Destination Address Register)
are aligned to byte.

controller operation

The dw_edma_core_ops structure contains a set of the operations:
device IRQ numbers getter, CPU/PCI address translation. Based on the
functions semantics the structure name "dw_edma_plat_ops" looks more
descriptive since indeed the operations are platform-specific. The
"dw_edma_core_ops" name shall be used for a structure with the IP-core
specific set of callbacks in order to abstract out DW eDMA and DW HDMA
setups. Such structure will be added in one of the next commit in the
framework of the set of changes adding the DW HDMA device support.
Anyway the renaming was necessary to distinguish two types of
the implementation callbacks:
1. DW eDMA/hDMA IP-core specific operations: device-specific CSR
setups in one or another aspect of the DMA-engine initialization.
2. DW eDMA/hDMA platform specific operations: the DMA device
environment configs like IRQs, address translation, etc.

A fixup for a printk format string warning causes an out-of-bounds

On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.
Here let QCOM_HIDMA depend on HAS_IOMEM so that it won't be built to
cause below compiling error if PCI is unset.

The call to phy_stop() races with the later call to phy_disconnect(),
resulting in concurrent phy_suspend() calls being run from different
CPUs. The final call to phy_disconnect() ensures that the PHY is
stopped and suspended, too.

In the current xdp_xmit implementation, if any single frame fails to
transmit due to insufficient buffer descriptors, the function nevertheless
reports success in sending all frames. This results in erroneously
indicating that frames were transmitted when in fact they were dropped.
This patch fixes the issue by ensureing the return value properly
indicates the actual number of frames successfully transmitted, rather than
potentially reporting success for all frames when some could not transmit.

On mt753x_cpu_port_enable() there's code that enables flooding for the CPU
port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports
are enabled, port 6 becomes the only port to forward the frames to. But
port 5 is the active port, so no frames received from the user ports will
be forwarded to port 5 which breaks network connectivity.
Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix
this issue by setting the bit that corresponds to the CPU port without
overwriting the other bits.
Clear the bits beforehand only for the MT7531 switch. According to the
documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference
Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and
UNU_FFP bits are set to 1 for MT7531, 0 for MT7530.
The commit 5e5502e012b8 ("net: dsa: mt7530: fix roaming from DSA user
ports") silently changed the method to set the bits on the MT7530_MFC.
Instead of clearing the relevant bits before mt7530_cpu_port_enable()
which runs under a for loop, the commit started doing it on
mt7530_cpu_port_enable().
Back then, this didn't really matter as only a single CPU port could be
used since the CPU port number was hardcoded. The driver was later changed
with commit 1f9a6abecf53 ("net: dsa: mt7530: get cpu-port via dp->cpu_dp
instead of constant") to retrieve the CPU port via dp->cpu_dp. With that,
this silent change became an issue for when using multiple CPU ports.

The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.
This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.
My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.
Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.
Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.
Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.
