pci_intx() is a hybrid function which can sometimes be managed through
devres. To remove this hybrid nature from pci_intx(), it is necessary to
port users to either an always-managed or a never-managed version.
cardreader/rtsx_pcr.c and tifm_7xx1.c enable their PCI devices with
pci_enable_device(). Thus, they need the never-managed version.

pci_intx() is a hybrid function which sometimes performs devres operations,
depending on whether pcim_enable_device() has been used to enable the
pci_dev. This sometimes-managed nature of the function is problematic.
Notably, it causes the function to allocate under some circumstances which
makes it unusable from interrupt context.
Export pcim_intx() (which is always managed) and rename __pcim_intx()
(which is never managed) to pci_intx_unmanaged() and export it as well.
Then all callers of pci_intx() can be ported to the version they need,
depending whether they use pci_enable_device() or pcim_enable_device().

It's safe to send PME_TURN_OFF message regardless of whether the link is up
or down, so don't test the LTSSM state before sending the PME_TURN_OFF
message.
Only print an error message when the LTSSM is not in DETECT or POLL. There
shouldn't be an error when no Endpoint is connected at all.

On the i.MX8QM, PCIe link can't be re-established again in

So, add dw_pcie_stop_link() to dw_pcie_suspend_noirq() to fix

The Root Complex specific device tree binding for pcie-dw-rockchip has the
'sys' interrupt marked as required.
The driver requests the 'sys' IRQ unconditionally, and errors out if not
provided.
Thus, we can unconditionally set 'use_linkup_irq', so dw_pcie_host_init()
doesn't wait for the link to come up.
This will skip the wait for link up (since the bus will be enumerated once
the link up IRQ is triggered), which reduces the bootup time.

Most boards using the pcie-dw-rockchip PCIe controller lack standard
hotplug support.
Thus, when an endpoint is attached to the SoC, users have to rescan the bus
manually to enumerate the device. This can be avoided by using the
'dll_link_up' interrupt in the combined system interrupt 'sys'.
Once the 'dll_link_up' IRQ is received, the bus underneath the host bridge
is scanned to enumerate PCIe endpoint devices.
This implements the same functionality that was implemented in the DWC
based pcie-qcom driver in 4581403f6792 ("PCI: qcom: Enumerate endpoints
based on Link up event in 'global_irq' interrupt").
The Root Complex specific device tree binding for pcie-dw-rockchip already
has the 'sys' interrupt marked as required, so there is no need to update
the device tree binding. This also means that we can request the 'sys' IRQ
unconditionally.

4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in
'global_irq' interrupt") added the Link Up-based enumeration support, but
did not update the ICC/OPP vote once link is up. Before that, the update
happened during probe and the endpoints may or may not be enumerated at
that time, so the ICC/OPP vote was not guaranteed to be accurate.
With Link Up-based enumeration support, the driver can request the accurate
vote based on the PCIe link.
Call qcom_pcie_icc_opp_update() in qcom_pcie_global_irq_thread() after
enumerating the endpoints.

Add an u64 hardware timestamping statistics structure for each ocelot
port. Export a function from the common switch library for reporting
them to ethtool. This is called by the ocelot switchdev front-end for

Note that for the switchdev driver, we report the one-step PTP packets
as unconfirmed, even though in principle, for some transmission
mechanisms like FDMA, we may be able to confirm transmission and bump
the "pkts" counter in ocelot_fdma_tx_cleanup() instead. I don't have
access to hardware which uses the switchdev front-end, and I've kept the

Tx header should be added to all packets transmitted from the CPU to
Spectrum ASICs. Historically, handling this header was added as a driver
function, as Tx header is different between Spectrum and Switch-X. See
SwitchX implementation in commit 31557f0f9755 ("mlxsw: Introduce
Mellanox SwitchX-2 ASIC support"). From May 2021, there is no support
for SwitchX-2 ASIC, and all the relevant code was removed.
For now, there is no justification to handle Tx header as part of
spectrum.c, we can handle this as part of PCI, in skb_transmit().
A future patch set will add support for XDP in mlxsw driver, to support
XDP_TX and XDP_REDIRECT actions, Tx header should be added before
transmitting the packet. As preparation for this, move Tx header handling
to PCI driver, so then XDP code will not have to call API from spectrum.c.
This also improves the code as now Tx header is pushed just before
transmitting, so it is not done from many flows which might miss something.
Note that for PTP, we should configure Tx header differently, use the
fields from mlxsw_txhdr_info to configure the packets correctly in PCI
driver. Handle VLAN tagging in switch driver, verify that packet which
should be transmitted as data is tagged, otherwise, tag it.
Remove the calls for thxdr_construct() functions, as now this is done as
part of skb_transmit().

A next patch will construct Tx header as part of pci.c. The switch driver
(mlxsw_spectrum.ko) should encapsulate all the differences between the
different ASICs and the bus driver (mlxsw_pci.ko) should remain unaware.
As preparation, add the relevant info as part of mlxsw_txhdr_info
structure, so later bus driver will merely construct the Tx header based on
information passed from the switch driver.
Most of the packets are transmitted as control packets, but PTP packets in
Spectrum-2 and Spectrum-3 should be handled differently. The driver
transmits them as data packets, and the default VLAN tag (4095) is added if
the packet is not already tagged.
Extend PTP operations to store a boolean which indicates whether packets
should be transmitted as data packets. Set it for Spectrum-2 and
Spectrum-3 only. Extend mlxsw_txhdr_info to store fields which will be used
later to construct Tx header. Initialize such fields according to the new
boolean which is stored in PTP operations.
Note that for now, mlxsw_txhdr_info structure is initialized, but not used,
a next patch will use it.

Shifting dest_attr->vport.vhca_id << 16 results in a promotion from an

extended to a 64 bit unsigned long on 64 bitarchitectures. If vhca_id is
greater than 0x7fff then this leads to a sign extended result where all
the upper 32 bits of idx are set to 1. Fix this by casting vhca_id

Pull mtd revert from Miquel Raynal:
"Very late this cycle we identified a breakage that could potentially
hit several spi controller drivers because of a change in the way the
dummy cycles validity is checked.
We do not know at the moment how to handle the situation properly, so
we prefer to revert the faulty patch for the next release"

Currently only stacked devices need to explicitly enable atomic writes by
setting BLK_FEAT_ATOMIC_WRITES_STACKED flag.
This does not work well for device mapper stacking devices, as there many
sets of limits are stacked and what is the 'bottom' and 'top' device can
swapped. This means that BLK_FEAT_ATOMIC_WRITES_STACKED needs to be set
for many queue limits, which is messy.
Generalize enabling atomic writes enabling by ensuring that all devices
must explicitly set a flag - that includes NVMe, SCSI sd, and md raid.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

In order to protect the platform_profile_handler from API consumers,
allocate it in platform_profile_register() and modify it's signature
accordingly.
Remove the platform_profile_handler from all consumer drivers and
replace them with a pointer to the class device, which is
now returned from platform_profile_register().
Replace *pprof with a pointer to the class device in the rest of
