Cooled SFP+ transceivers need a longer initialisation (startup) time.
Select the initialisation time depending on the cooled option bit.

phy_error() is called from phy_interrupt() or phy_state_machine(), and
uses WARN_ON() to print a backtrace. The backtrace is not useful when
reporting a PHY error.
However, a system may contain multiple ethernet PHYs, and phy_error()
gives no clue which one caused the problem.
Replace WARN_ON() with a call to phydev_err() so that we can see which
PHY had an error, and also inform the user that we are halting the PHY.

Allow the PHY to probe when there is no firmware, but do not allow the

Provide phy driver start/stop hooks so that the PHY driver knows when
the network driver is starting or stopping. This will be used for the
Marvell 10G driver so that we can sanely refuse to start if the PHYs
firmware is not present, and also so that we can sanely support SFPs
behind the PHY.

Add support for configuring the LEDs. Macchiatobin has an oddity in
that the left LED goes out when the cable is connected, and flashes
when there's link activity. This is because the reset default for
the LED outputs assume that the LED is connected to supply, not to
ground. Add support for configuring the LED modes and polarities.

There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

The at803x driver contains a function, at803x_match_phy_id(), which
tests whether the PHY ID matches the value passed, comparing phy_id
with phydev->phy_id and testing all bits that have a "one" in the
mask, phydev->drv->phy_id_mask.
This is the same test that is used to match the driver, with phy_id
replaced with the driver specified ID, phydev->drv->phy_id.
Hence, we already know the value of the bits being tested if we look
at phydev->drv->phy_id directly, and we do not require a complicated
test to check them. Test directly against phydev->drv->phy_id instead.

The SGMII PCS PHY needs to be updated with the link configuration in
the mac_link_up() call rather than in mac_config(). However,
mtk_sgmii_setup_mode_force() programs the SGMII block during
mac_config() when using 802.3z interface modes with the link
configuration.
Split that functionality from mtk_sgmii_setup_mode_force(), moving it
to a new mtk_sgmii_link_up() function, and call it from mac_link_up().
This does not look correct to me: 802.3z modes operate at a fixed
speed. The contents of mtk_sgmii_link_up() look more appropriate for
SGMII mode, but the original code definitely did not call
mtk_sgmii_setup_mode_force() for SGMII mode but only 802.3z mode.

Implement the .phylink_get_interfaces method for mv88e6xxx driver.
We are currently only interested in SGMII, 1000base-x and 2500base-x
modes (for the SFP code). USXGMII and 10gbase-r can be added later for
Amethyst. XAUI and RXAUI are irrelevant for SFP (but maybe not for

We currently parse the SFP EEPROM to a bitmap of ethtool link modes,
and then attempt to convert the link modes to a PHY interface mode.
While this works at present, there are cases where this is sub-optimal.
For example, where a module can operate with several different PHY
interface modes.
To start addressing this, arrange for the SFP EEPROM parsing to also
provide a bitmap of the possible PHY interface modes.

enabled GPIO pin number and label in debugfs for pin controller. However,
it limited that feature to the chips where base is positive number. This,

As we are using cpu_pm to save and restore context, we must also save and
restore the GPIO sysconfig register. This is needed because we are not
calling PM runtime functions at all with cpu_pm.
We need to save the sysconfig on idle as it's value can get reconfigured by
PM runtime and can be different from the init time value. Device specific
flags like "ti,no-idle-on-init" can affect the init value.

In case AUX failures happen unexpectedly during a modeset, the driver
should still complete the modeset. In particular the driver should
perform the link training sequence steps even in case of an AUX failure,
as this sequence also includes port initialization steps. Not doing that
can leave the port/pipe in a broken state and lead for instance to a
flip done timeout.
Fix this by continuing with link training (in a no-LTTPR mode) if the
DPRX DPCD readout failed for some reason at the beginning of link
training. After a successful connector detection we already have the
DPCD read out and cached, so the failed repeated read for it should not
cause a problem. Note that a partial AUX read could in theory partly
overwrite the cached DPCD (and return error) but this overwrite should
not happen if the returned values are corrupted (due to a timeout or
some other IO error).
Kudos to Ville to root cause the problem.

alignment in block mode
Since commit e085b51c74cc ("mmc: meson-gx: check for scatterlist size alignment in block mode"),
support for SDIO SD_IO_RW_EXTENDED transferts are properly filtered but some driver
like brcmfmac still gives a block sg buffer size not aligned with SDIO block,
triggerring a WARN_ONCE() with scary stacktrace even if the transfer works fine
but with possible degraded performances.
Simply replace with dev_warn_once() to inform user this should be fixed to avoid
degraded performance.
This should be ultimately fixed in brcmfmac, but since it's only a performance issue
the warning should be removed.

vmwgfx fixes for regressions in 5.12
Here's a set of 3 patches fixing ugly regressions
in the vmwgfx driver. We broke lock initialization
code and ended up using spinlocks before initialization
breaking lockdep.
Also there was a bit of a fallout from drm changes
which made the core validate that unreferenced buffers
have been unpinned. vmwgfx pinning code predates a lot
of the core drm and wasn't written to account for those
semantics. Fortunately changes required to fix it
are not too intrusive.
The changes have been validated by our internal ci.

Pull CXL memory class fixes from Dan Williams:
"A collection of fixes for the CXL memory class driver introduced in
this release cycle.
The driver was primarily developed on a work-in-progress QEMU
emulation of the interface and we have since found a couple places
where it hid spec compliance bugs in the driver, or had a spec
implementation bug itself.
The biggest change here is replacing a percpu_ref with an rwsem to
cleanup a couple bugs in the error unwind path during ioctl device
init. Lastly there were some minor cleanups to not export the
power-management sysfs-ABI for the ioctl device, use the proper sysfs
helper for emitting values, and prevent subtle bugs as new
administration commands are added to the supported list.
The bulk of it has appeared in -next save for the top commit which was
found today and validated on a fixed-up QEMU model.
Summary:
- Fix support for CXL memory devices with registers offset from the
BAR base.
- Fix the reporting of device capacity.
- Fix the driver commands list definition to be disconnected from the
UAPI command list.
- Replace percpu_ref with rwsem to fix initialization error path.
- Fix leaks in the driver initialization error path.
- Drop the power/ directory from CXL device sysfs.
- Use the recommended sysfs helper for attribute 'show'
implementations"

The CXL Identify Memory Device output payload emits capacity in 256MB
units. The driver is treating the capacity field as bytes. This was
missed because QEMU reports bytes when it should report bytes / 256MB.

The "Register Offset Low" register of a "DVSEC Register Locator"
contains the 64K aligned offset for the registers along with the BAR
indicator and an id. The implementation was treating the "Register Block
Offset Low" field a value rather than as a pre-aligned component of the
64-bit offset. So, just mask, don't mask and shift (FIELD_GET).
The user visible result of this bug is that the driver fails to bind to
the device after none of the required blocks are found.
This was missed earlier because the primary development done in the QEMU
environment only uses 0 offsets, i.e. 0 shifted is still 0.

snd_una update should not be done when the same skb is being
sent out.chcr_short_record_handler() sends it again even
though SND_UNA update is already sent for the skb in
chcr_ktls_xmit(), which causes mismatch in un-acked
TCP seq number, later causes problem in sending out
complete record.

Taking page refcount is not ideal and causes kernel panic
sometimes. It's better to take tx_ctx lock for the complete
skb transmit, to avoid page cleanup if ACK received in middle.
