[ Upstream commit 75221e9610 ]
An issue was present in the initial driver implementation. The driver
read the power status of all channels before toggling the bit of the
desired one. Using the power status register as a base value introduced
a problem, because only the bit corresponding to the concerned channel ID
should be set in the write-only power enable register. This led to cases
where disabling power for one channel also powered off other channels.
This patch removes the power status read and ensures the value is
limited to the bit matching the channel index of the PI.

Current implementation of stmmac_probe_config_dt() does not release the
OF node reference obtained by of_parse_phandle() in some error paths.
The problem is that some error paths call stmmac_remove_config_dt() to
clean up but others use and unwind ladder. These two types of error
handling have not kept in sync and have been a recurring source of bugs.
Re-write the error handling in stmmac_probe_config_dt() to use an unwind
ladder. Consequently, stmmac_remove_config_dt() is not needed anymore,
thus remove it.
This bug was found by an experimental verification tool that I am
developing.

[ Upstream commit 902806baf3 ]
AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

[ Upstream commit 25c6a5ab15 ]
On the i.MX6ULL-14x14-EVK board, enet1_ref and enet2_ref are used as the
clock sources for two external KSZ PHYs. However, after closing the two
FEC ports, the clk_enable_count of the enet1_ref and enet2_ref clocks is
not 0. The root cause is that since the commit 9853294627 ("net: phy:
micrel: use devm_clk_get_optional_enabled for the rmii-ref clock"), the
external clock of KSZ PHY has been enabled when the PHY driver probes,
and it can only be disabled when the PHY driver is removed. This causes
the clock to continue working when the system is suspended or the network
port is down.
Although Heiko explained in the commit message that the patch was because
some clock suppliers need to enable the clock to get the valid clock rate
, it seems that the simple fix is to disable the clock after getting the
clock rate to solve the current problem. This is indeed true, but we need
to admit that Heiko's patch has been applied for more than a year, and we
cannot guarantee whether there are platforms that only enable rmii-ref in
the KSZ PHY driver during this period. If this is the case, disabling
rmii-ref will cause RMII on these platforms to not work.
Secondly, commit 99ac4cbcc2 ("net: phy: micrel: allow usage of generic
ethernet-phy clock") just simply enables the generic clock permanently,
which seems like the generic clock may only be enabled in the PHY driver.
If we simply disable the generic clock, RMII may not work. If we keep it
as it is, the platform using the generic clock will have the same problem
as the i.MX6ULL platform.
To solve this problem, the clock is enabled when phy_driver::resume() is
called, and the clock is disabled when phy_driver::suspend() is called.
Since phy_driver::resume() and phy_driver::suspend() are not called in
pairs, an additional clk_enable flag is added. When phy_driver::suspend()
is called, the clock is disabled only if clk_enable is true. Conversely,
when phy_driver::resume() is called, the clock is enabled if clk_enable
is false.
The changes that introduced the problem were only a few lines, while the
current fix is about a hundred lines, which seems out of proportion, but
it is necessary because kszphy_probe() is used by multiple KSZ PHYs and
we need to fix all of them.

[ Upstream commit ebefac5647 ]
We initially introduced a quick fix limiting the queue depth to 1 as
experimentation showed that it fixed data corruption on 64GB steamdecks.
Further experimentation revealed corruption only happens when the last
PRP data element aligns to the end of the page boundary. The device
appears to treat this as a PRP chain to a new list instead of the data
element that it actually is. This implementation is in violation of the
spec. Encountering this errata with the Linux driver requires the host
request a 128k transfer and coincidently be handed the last small pool
dma buffer within a page.
The QD1 quirk effectly works around this because the last data PRP
always was at a 248 byte offset from the page start, so it never
appeared at the end of the page, but comes at the expense of throttling
IO and wasting the remainder of the PRP page beyond 256 bytes. Also to
note, the MDTS on these devices is small enough that the "large" prp
pool can hold enough PRP elements to never reach the end, so that pool
is not a problem either.
Introduce a new quirk to ensure the small pool is always aligned such
that the last PRP element can't appear a the end of the page. This comes
at the expense of wasting 256 bytes per small pool page allocated.

[ Upstream commit 79d330fbdf ]
Gen P7 supports up to 13 SGEs for now. WQE software structure
can hold only 6 now. Since the max send sge is reported as
13, the stack can give requests up to 13 SGEs. This is causing
traffic failures and system crashes.
Use the define for max SGE supported for variable size. This
will work for both static and variable WQEs.

commit afc6717628 upstream.
In order to catch a common bug where a TRACE_EVENT() TP_fast_assign()
assigns an address of an allocated string to the ring buffer and then
references it in TP_printk(), which can be executed hours later when the
string is free, the function test_event_printk() runs on all events as
they are registered to make sure there's no unwanted dereferencing.
It calls process_string() to handle cases in TP_printk() format that has
"%s". It returns whether or not the string is safe. But it can have some
false positives.
For instance, xe_bo_move() has:
TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s",
__entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size,
xe_mem_type_to_name[__entry->old_placement],
xe_mem_type_to_name[__entry->new_placement], __get_str(device_id))
Where the "%s" references into xe_mem_type_to_name[]. This is an array of
pointers that should be safe for the event to access. Instead of flagging
this as a bad reference, if a reference points to an array, where the
record field is the index, consider it safe.

commit f64f610ec6 upstream.
The genpd device, which is really only used as a handle to lookup
OPP, but not even registered to the device core otherwise and thus
lifetime linked to the genpd struct it is contained in, is missing
a release function. After b8f7bbd1f4 ("pmdomain: core: Add
missing put_device()") the device will be cleaned up going through
the driver core device_release() function, which will warn when no
release callback is present for the device. Add a dummy release
function to shut up the warning.

commit 032fe9b051 upstream.
The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN
thermal profile and requires the timed profile quirk.
Upon adding this ID to both the omen_thermal_profile_boards and
omen_timed_thermal_profile_boards, significant bump in performance can be
observed. For instance, SilverBench (https://silver.urih.com/) results
improved from ~56,000 to ~69,000, as a result of higher power draws (and
thus core frequencies) whilst under load:
Package Power:
- Before the patch: ~65W (dropping to about 55W under sustained load).
- After the patch: ~115W (dropping to about 105W under sustained load).
Core Power:
- Before: ~60W (ditto above).
- After: ~108W (ditto above).
Add 8A15 to omen_thermal_profile_boards and
omen_timed_thermal_profile_boards to improve performance.
