net: phy: mscc: support VSC8501
this updated series of patches adds support for the VSC8501 Ethernet
PHY and fixes support for the VSC8502 PHY in cases where no other
software (like U-Boot) has initialized the PHY after power up.
The first patch simply adds the VSC8502 to the MODULE_DEVICE_TABLE,
where I guess it was unintentionally missing. I have no hardware to
test my change.
The second patch adds the VSC8501 PHY with exactly the same driver
implementation as the existing VSC8502.
The (new) third patch removes phydev locking from
vsc85xx_rgmii_set_skews(), as discussed for v2 of the patch set.
The (now) fourth patch fixes the initialization for VSC8501 and VSC8502.
I have tested this patch with VSC8501 on hardware in RGMII mode only.
https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8501-03_Datasheet_60001741A.PDFhttps://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8502-03_Datasheet_60001742B.pdf
Table 4-42 "RGMII CONTROL, ADDRESS 20E2 (0X14)" Bit 11 for each of
them.
By default the RX_CLK is disabled for these PHYs. In cases where no
other software, like U-Boot, enabled the clock, this results in no
received packets being handed to the MAC.
The patch enables this clock output.
According to Microchip support (case number 01268776) this applies
to all modes (RGMII, GMII, and MII).
Other PHYs sharing the same register map and code, like
VSC8530/31/40/41 have the clock enabled and the relevant bit 11 is
reserved and read-only for them. As per previous discussion the
patch still clears the bit on these PHYs, too, possibly more easily
supporting other future PHYs implementing this functionality.
For the VSC8572 family of PHYs, having a different register map,
no such changes are applied.

By default the VSC8501 and VSC8502 RGMII/GMII/MII RX_CLK output is
disabled. To allow packet forwarding towards the MAC it needs to be
enabled.
For other PHYs supported by this driver the clock output is enabled
by default.

Holding the struct phy_device (phydev) lock is unnecessary when
accessing phydev->interface in the PHY driver .config_init method,
which is the only place that vsc85xx_rgmii_set_skews() is called from.
The phy_modify_paged() function implements required MDIO bus level
locking, which can not be achieved by a phydev lock.

Bug fixes for net/handshake
Paolo observed that there is a possible leak of sock->file. I
haven't looked into that yet, but it seems to be separate from
the fixes in this series, so no need to hold these up.
====================
The submissions mentions net-next but it means netdev (perhaps
merge window left over when trees are converged). In any case,
it should have gone into net, but was instead applied to net-next
as commit deb2e484baf9 ("Merge branch 'net-handshake-fixes'").
These are fixes tho, and Chuck needs them to make progress with
the client so double-merging them into net... it is what it is :(

As part of switchdev mode disablement, driver changes port netdevice
profile from uplink to nic. If this process is triggered by health
recovery flow (PCI reset, for ex.) profile attach would fail because all
fw commands aborted when internal error flag is set. As a result, nic
netdevice profile is not attached and driver fails to rollback to uplink
profile, which leave driver in broken state and cause crash later.
To handle broken state do netdevice profile initialization only instead
of full attachment and release mdev resources on driver suspend as
expected. Actual netdevice attachment is done during driver load.

Caller of mlx5e_tc_act_post_parse() needs it to parse only the subset of
actions starting after previous split and ending at the current action.
However, that range is not provided as arguments and
mlx5e_tc_act_post_parse() uses generic flow_action_for_each() that iterates
over all flow actions. Not only this is redundant, it also causes a bug
when mlx5e_tc_act->post_parse() callback is not idempotent since it will be
called for every split. For example, ct action tc_act_post_parse_ct()
callback obtains a reference to mlx5_ct_ft instance and calling it several
times during parsing stage will cause reference counter imbalance.
Fix the issue by providing a proper action range of the current split
subset to mlx5e_tc_act_post_parse() and only calling
mlx5e_tc_act->post_parse() for actions inside the subset range.

register are updated when the user changes the prio2buffer mapping.
However, in case the user desired prio2buffer change is invalid,
which can occur due to mapping a lossless priority to a not large enough
buffer, the SBCM update should not be performed, as the user command is
failed.

Currently, when a user triggers a change in port buffer headroom
(buffers 0-7), the driver checks that the requested headroom does
not exceed the total port buffer size. However, this check does not
take into account the internal buffers (buffers 8-9), which are also
part of the total port buffer. This can result in treating invalid port
buffer change requests as valid, causing unintended changes to the shared
buffer.
To address this, include the internal buffers size in the calculation of
available port buffer space which ensures that port buffer requests do not
exceed the correct limit.
Furthermore, remove internal buffers (8-9) size from the total_size
calculation as these buffers are reserved for internal use and are not
exposed to the user.
While at it, add verbosity to the debug prints in
mlx5e_port_query_buffer() function to ease future debugging.

entry's flows list. If neigh update is running at this time, the
following encaps of the flow can't hold the encap_tbl_lock and
sleep. If neigh update thread is waiting for that flow's init_done,
deadlock happens.
Fix it by holding lock outside of the for loop. If neigh update is

There are two ways that special characters (not allowed in some
other operating systems like Windows, but allowed in POSIX) have
been mapped in the past ("SFU" and "SFM" mappings) to allow them
to be stored in a range reserved for special chars. The default
for Linux has been to use "mapposix" (ie the SFM mapping) but
the conversion to the new mount API in the 5.11 kernel broke
the ability to override the default mapping of the reserved
characters (like '?' and '*' and '\') via "mapchars" mount option.
This patch fixes that - so can now mount with "mapchars"
mount option to override the default ("mapposix" ie SFM) mapping.

cifs.ko maps NT_STATUS_NOT_FOUND to -EIO when SMB1 servers couldn't
resolve referral paths. Proceed to tree connect when we get -EIO from
dfs_get_referral() as well.

At drm suspend sequence, MST dc_sink is removed. When commit cached
MST stream back in drm resume sequence, the MST stream payload is not
properly created and added into the payload table. After resume, topology
change is reprobed by removing existing streams first. That leads to
no payload is found in the existing payload table as below error
"[drm] ERROR No payload for [MST PORT:] found in mst state"
1. In encoder .atomic_check routine, remove check existance of dc_sink
2. Bypass MST by checking existence of MST root port. dc_link_type cannot
differentiate MST port before topology is rediscovered.

[Why]
During gpu-reset, we toggle vblank irq by calling dc_interrupt_set()
instead of amdgpu_irq_get/put() because we don't want to change the irq
source's refcount. However, we see the warning when vblank irq is enabled
by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put()
after gpu-reset.
[How]
Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by
calling dc_interrupt_set(). Apart from this we call dm_set_vblank()
which uses amdgpu_irq_get/put() to operate vblank irq.

The number of CHAs from the discovery table on some SPR variants is
incorrect, because of a firmware issue. An accurate number can be read
from the MSR UNC_CBO_CONFIG.

Printing the other clock types should not be conditioned on being able
to print OD_SCLK. Some GPUs currently have limited capability of only
printing a subset of these.
Since this condition was introduced in v5.18-rc1, reading from
`pp_od_clk_voltage` has been returning empty on the Asus ROG Strix G15
(2021).

Put back the radeon_dp_work_func logic. It seems that
handling DP RX interrupts is necessary to make some
panels work. This was removed with the MST support,
but it regresses some systems so add it back. While
we are here, add the proper mutex locking.

A collection of fixes that came in since the merge window, plus an
update to MAINTAINERS. The Cadence fixes are coming from the addition
of device mode support, they required a couple of incremental updates in
order to get something that works robustly for both device and
controller modes.

Prior to the commit "763bd29fd3d1 ("thermal: int340x_thermal: Use
sysfs_emit_at() instead of scnprintf()", there was a new line after each
UUID string.
With the newline removed, existing user space like "thermald" fails to
compare each supported UUID as it is using getline() to read UUID and
apply correct thermal table.
To avoid breaking existing user space, add newline after each UUID string.
