Since commit b39648079db4 ("net: mscc: ocelot: disable flow control on
NPI interface"), flow control should be disabled on the DSA CPU port
when used in NPI mode.
However, the commit blamed in the Fixes: tag below broke this, because
it allowed felix_phylink_mac_link_up() to overwrite SYS_PAUSE_CFG_PAUSE_ENA
for the DSA CPU port.
This issue became noticeable since the device tree update from commit
8fcea7be5736 ("arm64: dts: ls1028a: mark internal links between Felix
and ENETC as capable of flow control").
The solution is to check whether this is the currently configured NPI
port from ocelot_phylink_mac_link_up(), and to not modify the statically
disabled PAUSE frame transmission if it is.
When the port is configured for lossless mode as opposed to tail drop
mode, but the link partner (DSA master) doesn't observe the transmitted
PAUSE frames, the switch termination throughput is much worse, as can be
seen below.

Pull clk updates from Stephen Boyd:
"We have a couple patches in the framework core this time around but
they're mostly minor cleanups and some debugfs stuff. The real work
that's in here is the typical pile of clk driver updates and new SoC
support.
Per usual (or maybe just recent trends), Qualcomm gains a handful of
SoC drivers additions and has the largest diffstat. After that there
are quite a few updates to the Allwinner (sunxi) drivers to support
modular drivers and Renesas is heavily updated to add more support for
various clks.
Overall it looks pretty normal.
New Drivers:
- Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770
- MediaTek mt7986 SoC basic support
- Clock and reset driver for Toshiba Visconti SoCs
- Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8)
- Allwinner D1 clks
- Lan966x Generic Clock Controller driver and associated DT bindings
- Qualcomm SDX65, SM8450, and MSM8976 GCC clks
- Qualcomm SDX65 and SM8450 RPMh clks
Updates:
- Set suppress_bind_attrs to true for i.MX8ULP driver
- Switch from do_div to div64_ul for throughout all i.MX drivers
- Fix imx8mn_clko1_sels for i.MX8MN
- Remove unused IPG_AUDIO_ROOT from i.MX8MP
- Switch parent for audio_root_clk to audio ahb in i.MX8MP driver

Pull dax and libnvdimm updates from Dan Williams:
"The bulk of this is a rework of the dax_operations API after
discovering the obstacles it posed to the work-in-progress DAX+reflink
support for XFS and other copy-on-write filesystem mechanics.
Primarily the need to plumb a block_device through the API to handle
partition offsets was a sticking point and Christoph untangled that
dependency in addition to other cleanups to make landing the
DAX+reflink support easier.
The DAX_PMEM_COMPAT option has been around for 4 years and not only
are distributions shipping userspace that understand the current
configuration API, but some are not even bothering to turn this option
on anymore, so it seems a good time to remove it per the deprecation
schedule. Recall that this was added after the device-dax subsystem
moved from /sys/class/dax to /sys/bus/dax for its sysfs organization.
All recent functionality depends on /sys/bus/dax.
Some other miscellaneous cleanups and reflink prep patches are
included as well.
Summary:
- Simplify the dax_operations API:
- Eliminate bdev_dax_pgoff() in favor of the filesystem
maintaining and applying a partition offset to all its DAX iomap
operations.
- Remove wrappers and device-mapper stacked callbacks for
->copy_from_iter() and ->copy_to_iter() in favor of moving
block_device relative offset responsibility to the
dax_direct_access() caller.
- Remove the need for an @bdev in filesystem-DAX infrastructure
- Remove unused uio helpers copy_from_iter_flushcache() and
copy_mc_to_iter() as only the non-check_copy_size() versions are
used for DAX.
- Prepare XFS for the pending (next merge window) DAX+reflink support
- Remove deprecated DEV_DAX_PMEM_COMPAT support

When pci_register_host_bridge() is called, bridge->windows are already
available. However these windows are being moved temporarily from there.
To let pcibios_root_bridge_prepare() have access to these windows, move the
windows movement after calling this function. This is useful for the MIPS
ralink mt7621 platform so it can set up I/O coherence units and avoid
custom MIPS code in the mt7621 PCIe controller driver.

This Broadcom STB PCIe RC driver has one port and connects directly to one
device, be it a switch or an endpoint. We want to be able to leverage the
recently added mechanism that allocates and turns on/off subdevice
regulators.
All that needs to be done is to put the regulator DT nodes in the bridge
below host and to set the pci_ops methods add_bus and remove_bus.
Note that the pci_subdev_regulators_add_bus() method is wrapped for two
reasons:
1. To achieve link up after the voltage regulators are turned on.
2. If, in the case of an unsuccessful link up, to redirect any PCIe
accesses to subdevices, e.g. the scan for DEV/ID. This redirection
is needed because the Broadcom PCIe HW will issue a CPU abort if such
an access is made when the link is down.

Add a mechanism to identify standard PCIe regulators in the DT, allocate
them, and turn them on before the rest of the bus is scanned during
pci_host_probe().
The allocated structure that contains the regulators is stored in the port
driver dev.driver_data field. Here is a point-by-point of how and when
this mechanism is activated:
If:
-- PCIe RC driver sets pci_ops {add,remove)_bus to
pci_subdev_regulators_{add,remove}_bus during its probe.
-- There is a DT node "RB" under the host bridge DT node.
-- During the RC driver's pci_host_probe() the add_bus callback
is invoked where (bus->parent && pci_is_root_bus(bus->parent)
is true
Then:
-- A struct subdev_regulators structure will be allocated and
assigned to bus->dev.driver_data.
-- regulator_bulk_{get,enable} will be invoked on &bus->dev
and the former will search for and process any
vpcie{12v,3v3,3v3aux}-supply properties that reside in node "RB".
-- The regulators will be turned off/on for any unbind/bind operations.
-- The regulators will be turned off/on for any suspend/resumes, but
only if the RC driver handles this on its own. This will appear
in a later commit for the pcie-brcmstb.c driver.
The unabridged reason for doing this is as follows. We would like the
Broadcom STB PCIe root complex driver (and others) to be able to turn
off/on regulators[1] that provide power to endpoint[2] devices. Typically,
the drivers of these endpoint devices are stock Linux drivers that are not
aware that these regulator(s) exist and must be turned on for the driver to
be probed. The simple solution of course is to turn these regulators on at
boot and keep them on. However, this solution does not satisfy at least
three of our usage modes:
1. For example, one customer uses multiple PCIe controllers, but wants
the ability to, by script invoking and unbind, turn any or all of them
and their subdevices off to save power, e.g. when in battery mode.
2. Another example is when a watchdog script discovers that an endpoint
device is in an unresponsive state and would like to unbind, power
toggle, and re-bind just the PCIe endpoint and controller.
3. Of course we also want power turned off during suspend mode. However,
some endpoint devices may be able to "wake" during suspend and we need
to recognise this case and veto the nominal act of turning off its
regulator. Such is the case with Wake-on-LAN and Wake-on-WLAN support
where the PCIe endpoint device needs to be kept powered on in order to
receive network packets and wake the system.
In all of these cases it is advantageous for the PCIe controller to govern
the turning off/on the regulators needed by the endpoint device. The first
two cases can be done by simply unbinding and binding the PCIe controller,
if the controller has control of these regulators.
[1] These regulators typically govern the actual power supply to the
endpoint chip. Sometimes they may be the official PCIe socket
power -- such as 3.3v or aux-3.3v. Sometimes they are truly
the regulator(s) that supply power to the EP chip.
[2] The 99% configuration of our boards is a single endpoint device
attached to the PCIe controller. I use the term endpoint but it could
possibly mean a switch as well.

We need to take some code in brcm_pcie_setup() and put it in a new function
brcm_pcie_linkup(). In future commits the brcm_pcie_linkup() function will
be called indirectly by pci_host_probe() as opposed to the host driver
invoking it directly.
Some code that was executed after the PCIe linkup is now placed so that it
executes prior to linkup, since this code has to run prior to the
invocation of pci_host_probe().

The 'used' field of 'struct brcm_msi' is used as a bitmap. Declare it with
DECLARE_BITMAP() and adjust users accordingly.
This fixes a harmless Coverity warning about array vs singleton usage.
This bitmap can be used for either legacy or MSI interrupts, which require
a size of BRCM_INT_PCI_MSI_LEGACY_NR or BRCM_INT_PCI_MSI_NR respectively.
Add a BUILD_BUG_ON() to ensure it is large enough.
