[PATCH 5.10 03/52] ALSA: hda/tegra: Use clk_bulk helpers

[Greg Kroah-Hartman]

From: Dmitry Osipenko <digetx@gmail.com>

[ Upstream commit 3a465f027a33cbd2af74f882ad41729583195e8f ]

Use clk_bulk helpers to make code cleaner. Note that this patch changed
the order in which clocks are enabled to make code look nicer, but this
doesn't matter in terms of hardware.

[PATCH 5.10 05/52] ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically

[Greg Kroah-Hartman]

From: Hui Wang <hui.wang@canonical.com>

[ Upstream commit 13046370c4d143b629adc1a51659a8a6497fbbe6 ]

If the platform set the dyn_pcm_assign to true, it will call
hdmi_find_pcm_slot() to find a pcm slot when hdmi/dp monitor is
connected and need to create a pcm.

So far only intel_hsw_common_init() and patch_nvhdmi() set the
dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot
dynamically first, if the driver runs for a period of time and there
is no regression reported, we could set no_fixed_assgin to true in
the intel_hsw_common_init(), and then set it to true in the
patch_nvhdmi().

This change comes from the discussion between Takashi and
Kai Vehmanen. Please refer to:

[PATCH 5.10 06/52] ALSA: hda: Fix Nvidia dp infoframe

[Greg Kroah-Hartman]

From: Mohan Kumar <mkumard@nvidia.com>

[ Upstream commit f89e409402e2aeb3bc3aa44d2b7a597959e4e6af ]

Nvidia HDA HW expects infoframe data bytes order same for both
HDMI and DP i.e infoframe data starts from 5th bytes offset. As
dp infoframe structure has 4th byte as valid infoframe data, use
hdmi infoframe structure for nvidia dp infoframe to match HW behvaior.

What happens is the following:

1) The cleaner kthread tries to start a transaction to delete an unused
   block group, but the metadata reservation can not be satisfied right
   away, so a reservation ticket is created and it starts the async
   metadata reclaim task (fs_info->async_reclaim_work);

2) Writeback for all the filler inodes with an i_size of 2K starts
   (generic/562 creates a lot of 2K files with the goal of filling
   metadata space). We try to create an inline extent for them, but we
   fail when trying to insert the inline extent with -ENOSPC (at
   cow_file_range_inline()) - since this is not critical, we fallback
   to non-inline mode (back to cow_file_range()), reserve extents, create
   extent maps and create the ordered extents;

3) An unmount starts, enters close_ctree();

4) The async reclaim task is flushing stuff, entering the flush states one
   by one, until it reaches RUN_DELAYED_IPUTS. There it runs all current
   delayed iputs.

   After running the delayed iputs and before calling
   btrfs_wait_on_delayed_iputs(), one or more ordered extents complete,
   and btrfs_add_delayed_iput() is called for each one through
   btrfs_finish_ordered_io() -> btrfs_put_ordered_extent(). This results
   in bumping fs_info->nr_delayed_iputs from 0 to some positive value.

   So the async reclaim task blocks at btrfs_wait_on_delayed_iputs() waiting
   for fs_info->nr_delayed_iputs to become 0;

5) The current transaction is committed by the transaction kthread, we then
   start unpinning extents and end up calling btrfs_try_granting_tickets()
   through unpin_extent_range(), since we released some space.
   This results in satisfying the ticket created by the cleaner kthread at
   step 1, waking up the cleaner kthread;

6) At close_ctree() we ask the cleaner kthread to park;

7) The cleaner kthread starts the transaction, deletes the unused block
   group, and then calls kthread_should_park(), which returns true, so it
   parks. And at this point we have the delayed iputs added by the
   completion of the ordered extents still pending;

8) Then later at close_ctree(), when we call:

       cancel_work_sync(&fs_info->async_reclaim_work);

   We hang forever, since the cleaner was parked and no one else can run
   delayed iputs after that, while the reclaim task is waiting for the
   remaining delayed iputs to be completed.

Fix this by waiting for all ordered extents to complete and running the
delayed iputs before attempting to stop the async reclaim tasks. Note that
we can not wait for ordered extents with btrfs_wait_ordered_roots() (or
other similar functions) because that waits for the BTRFS_ORDERED_COMPLETE
flag to be set on an ordered extent, but the delayed iput is added after
that, when doing the final btrfs_put_ordered_extent(). So instead wait for
the work queues used for executing ordered extent completion to be empty,
which works because we do the final put on an ordered extent at
btrfs_finish_ordered_io() (while we are in the unmount context).

[PATCH 5.10 08/52] uas: add no-uas quirk for Hiksemi usb_disk

[Greg Kroah-Hartman]

From: Hongling Zeng <zenghongling@kylinos.cn>

commit a625a4b8806cc1e928b7dd2cca1fee709c9de56e upstream.

The UAS mode of Hiksemi is reported to fail to work on several platforms
with the following error message, then after re-connecting the device will
be offlined and not working at all.

These disks have a broken uas implementation, the tag field of the status
iu-s is not set properly,so we need to fall-back to usb-storage.

[PATCH 5.10 09/52] usb-storage: Add Hiksemi USB3-FW to IGNORE_UAS

[Greg Kroah-Hartman]

From: Hongling Zeng <zenghongling@kylinos.cn>

commit e00b488e813f0f1ad9f778e771b7cd2fe2877023 upstream.

The UAS mode of Hiksemi USB_HDD is reported to fail to work on several
platforms with the following error message, then after re-connecting the
device will be offlined and not working at all.

These disks have a broken uas implementation, the tag field of the status
iu-s is not set properly,so we need to fall-back to usb-storage.

[PATCH 5.10 11/52] usb: typec: ucsi: Remove incorrect warning

[Greg Kroah-Hartman]

From: Heikki Krogerus <heikki.krogerus@linux.intel.com>

commit 415ba26cb73f7d22a892043301b91b57ae54db02 upstream.

Sink only devices do not have any source capabilities, so
the driver should not warn about that. Also DRP (Dual Role
Power) capable devices, such as USB Type-C docking stations,
do not return any source capabilities unless they are
plugged to a power supply themselves.

[PATCH 5.10 12/52] thunderbolt: Explicitly reset plug events delay back to USB4 spec value

[Greg Kroah-Hartman]

From: Mario Limonciello <mario.limonciello@amd.com>

commit 31f87f705b3c1635345d8e8a493697099b43e508 upstream.

If any software has interacted with the USB4 registers before the Linux
USB4 CM runs, it may have modified the plug events delay. It has been
observed that if this value too large, it's possible that hotplugged
devices will negotiate a fallback mode instead in Linux.

To prevent this, explicitly align the plug events delay with the USB4
spec value of 10ms.

[PATCH 5.10 14/52] Input: snvs_pwrkey - fix SNVS_HPVIDR1 register address

[Greg Kroah-Hartman]

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@puri.sm>

commit e62563db857f81d75c5726a35bc0180bed6d1540 upstream.

Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1
(chapters 57.9 and 6.4.5 respectively).

Without this, trying to read the revision number results in 0 on
all revisions, causing the i.MX6 quirk to apply on all platforms,
which in turn causes the driver to synthesise power button release
events instead of passing the real one as they happen even on
platforms like i.MX8 where that's not wanted.

[PATCH 5.10 15/52] clk: ingenic-tcu: Properly enable registers before accessing timers

[Greg Kroah-Hartman]

From: Aidan MacDonald <aidanmacdonald.0x0@gmail.com>

commit 6726d552a6912e88cf63fe2bda87b2efa0efc7d0 upstream.

Access to registers is guarded by ingenic_tcu_{enable,disable}_regs()
so the stop bit can be cleared before accessing a timer channel, but
those functions did not clear the stop bit on SoCs with a global TCU
clock gate.

Testing on the X1000 has revealed that the stop bits must be cleared
_and_ the global TCU clock must be ungated to access timer registers.
This appears to be the norm on Ingenic SoCs, and is specified in the
documentation for the X1000 and numerous JZ47xx SoCs.

If the stop bit isn't cleared, register writes don't take effect and
the system can be left in a broken state, eg. the watchdog timer may
not run.

The bug probably went unnoticed because stop bits are zeroed when
the SoC is reset, and the kernel does not set them unless a timer
gets disabled at runtime. However, it is possible that a bootloader
or a previous kernel (if using kexec) leaves the stop bits set and
we should not rely on them being cleared.

Fixing this is easy: have ingenic_tcu_{enable,disable}_regs() always
clear the stop bit, regardless of the presence of a global TCU gate.

Fix this by adding sanity check on extended system files' directory inode
to ensure that it is directory, just like ntfs_extend_init() when mounting
ntfs3.

[PATCH 5.10 18/52] net: mt7531: only do PLL once after the reset

[Greg Kroah-Hartman]

From: Alexander Couzens <lynxis@fe80.eu>

commit 42bc4fafe359ed6b73602b7a2dba0dd99588f8ce upstream.

Move the PLL init of the switch out of the pad configuration of the port
6 (usally cpu port).

Fix a unidirectional 100 mbit limitation on 1 gbit or 2.5 gbit links for
outbound traffic on port 5 or port 6.

[PATCH 5.10 19/52] powerpc/64s/radix: dont need to broadcast IPI for radix pmd collapse flush

[Greg Kroah-Hartman]

From: Yang Shi <shy828301@gmail.com>

commit bedf03416913d88c796288f9dca109a53608c745 upstream.

The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will
move to use RCU instead of disabling local interrupts in fast-GUP.  Using
an IPI is the old-styled way of serializing against fast-GUP although it
still works as expected now.

And fast-GUP now fixed the potential race with THP collapse by checking
whether PMD is changed or not.  So IPI broadcast in radix pmd collapse
flush is not necessary anymore.  But it is still needed for hash TLB.

[PATCH 5.10 20/52] libata: add ATA_HORKAGE_NOLPM for Pioneer BDR-207M and BDR-205

[Greg Kroah-Hartman]

From: Niklas Cassel <niklas.cassel@wdc.com>

commit ea08aec7e77bfd6599489ec430f9f859ab84575a upstream.

Commit 1527f69204fe ("ata: ahci: Add Green Sardine vendor ID as
board_ahci_mobile") added an explicit entry for AMD Green Sardine
AHCI controller using the board_ahci_mobile configuration (this
configuration has later been renamed to board_ahci_low_power).

The board_ahci_low_power configuration enables support for low power
modes.

This explicit entry takes precedence over the generic AHCI controller
entry, which does not enable support for low power modes.

Therefore, when commit 1527f69204fe ("ata: ahci: Add Green Sardine
vendor ID as board_ahci_mobile") was backported to stable kernels,
it make some Pioneer optical drives, which was working perfectly fine
before the commit was backported, stop working.

The real problem is that the Pioneer optical drives do not handle low
power modes correctly. If these optical drives would have been tested
on another AHCI controller using the board_ahci_low_power configuration,
this issue would have been detected earlier.

Unfortunately, the board_ahci_low_power configuration is only used in
less than 15% of the total AHCI controller entries, so many devices
have never been tested with an AHCI controller with low power modes.

[PATCH 5.10 21/52] mmc: moxart: fix 4-bit bus width and remove 8-bit bus width

[Greg Kroah-Hartman]

From: Sergei Antonov <saproj@gmail.com>

commit 35ca91d1338ae158f6dcc0de5d1e86197924ffda upstream.

According to the datasheet [1] at page 377, 4-bit bus width is turned on by
bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define
BUS_WIDTH_4 BIT(1)

BIT(1) does not work but BIT(2) works. This has been verified on real MOXA
hardware with FTSDC010 controller revision 1_6_0.

The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8
BIT(2). Additionally, 8-bit bus width mode isn't supported according to the
datasheet, so let's remove the corresponding code.

[PATCH 5.10 22/52] mmc: hsq: Fix data stomping during mmc recovery

[Greg Kroah-Hartman]

From: Wenchao Chen <wenchao.chen@unisoc.com>

commit e7afa79a3b35a27a046a2139f8b20bd6b98155c2 upstream.

The block device uses multiple queues to access emmc. There will be up to 3
requests in the hsq of the host. The current code will check whether there
is a request doing recovery before entering the queue, but it will not check
whether there is a request when the lock is issued. The request is in recovery
mode. If there is a request in recovery, then a read and write request is
initiated at this time, and the conflict between the request and the recovery
request will cause the data to be trampled.

[PATCH 5.10 23/52] mm/page_alloc: fix race condition between build_all_zonelists and page allocation

[Greg Kroah-Hartman]

From: Mel Gorman <mgorman@techsingularity.net>

commit 3d36424b3b5850bd92f3e89b953a430d7cfc88ef upstream.

Patrick Daly reported the following problem;

	NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - before offline operation
	[0] - ZONE_MOVABLE
	[1] - ZONE_NORMAL
	[2] - NULL

	For a GFP_KERNEL allocation, alloc_pages_slowpath() will save the
	offset of ZONE_NORMAL in ac->preferred_zoneref. If a concurrent
	memory_offline operation removes the last page from ZONE_MOVABLE,
	build_all_zonelists() & build_zonerefs_node() will update
	node_zonelists as shown below. Only populated zones are added.

	NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - after offline operation
	[0] - ZONE_NORMAL
	[1] - NULL
	[2] - NULL

The race is simple -- page allocation could be in progress when a memory
hot-remove operation triggers a zonelist rebuild that removes zones.  The
allocation request will still have a valid ac->preferred_zoneref that is
now pointing to NULL and triggers an OOM kill.

This problem probably always existed but may be slightly easier to trigger
due to 6aa303defb74 ("mm, vmscan: only allocate and reclaim from zones
with pages managed by the buddy allocator") which distinguishes between
zones that are completely unpopulated versus zones that have valid pages
not managed by the buddy allocator (e.g.  reserved, memblock, ballooning
etc).  Memory hotplug had multiple stages with timing considerations
around managed/present page updates, the zonelist rebuild and the zone
span updates.  As David Hildenbrand puts it

	memory offlining adjusts managed+present pages of the zone
	essentially in one go. If after the adjustments, the zone is no
	longer populated (present==0), we rebuild the zone lists.

	Once that's done, we try shrinking the zone (start+spanned
	pages) -- which results in zone_start_pfn == 0 if there are no
	more pages. That happens *after* rebuilding the zonelists via
	remove_pfn_range_from_zone().

The only requirement to fix the race is that a page allocation request
identifies when a zonelist rebuild has happened since the allocation
request started and no page has yet been allocated.  Use a seqlock_t to
track zonelist updates with a lockless read-side of the zonelist and
protecting the rebuild and update of the counter with a spinlock.

[PATCH 5.10 24/52] mm: prevent page_frag_alloc() from corrupting the memory

[Greg Kroah-Hartman]

From: Maurizio Lombardi <mlombard@redhat.com>

commit dac22531bbd4af2426c4e29e05594415ccfa365d upstream.

A number of drivers call page_frag_alloc() with a fragment's size >
PAGE_SIZE.

In low memory conditions, __page_frag_cache_refill() may fail the order
3 cache allocation and fall back to order 0; In this case, the cache
will be smaller than the fragment, causing memory corruptions.

Prevent this from happening by checking if the newly allocated cache is
large enough for the fragment; if not, the allocation will fail and
page_frag_alloc() will return NULL.

From: Alistair Popple <apopple@nvidia.com>

commit 60bae73708963de4a17231077285bd9ff2f41c44 upstream.

When clearing a PTE the TLB should be flushed whilst still holding the PTL
to avoid a potential race with madvise/munmap/etc.  For example consider
the following sequence:

  CPU0                          CPU1
  ----                          ----

  migrate_vma_collect_pmd()
  pte_unmap_unlock()
                                madvise(MADV_DONTNEED)
                                -> zap_pte_range()
                                pte_offset_map_lock()
                                [ PTE not present, TLB not flushed ]
                                pte_unmap_unlock()
                                [ page is still accessible via stale TLB ]
  flush_tlb_range()

In this case the page may still be accessed via the stale TLB entry after
madvise returns.  Fix this by flushing the TLB while holding the PTL.

[PATCH 5.10 26/52] mm: fix madivse_pageout mishandling on non-LRU page

[Greg Kroah-Hartman]

From: Minchan Kim <minchan@kernel.org>

commit 58d426a7ba92870d489686dfdb9d06b66815a2ab upstream.

MADV_PAGEOUT tries to isolate non-LRU pages and gets a warning from
isolate_lru_page below.

Fix it by checking PageLRU in advance.

[PATCH 5.10 28/52] media: rkvdec: Disable H.264 error detection

[Greg Kroah-Hartman]

From: Nicolas Dufresne <nicolas.dufresne@collabora.com>

commit 3a99c4474112f49a5459933d8758614002ca0ddc upstream.

Quite often, the HW get stuck in error condition if a stream error
was detected. As documented, the HW should stop immediately and self
reset. There is likely a problem or a miss-understanding of the self
reset mechanism, as unless we make a long pause, the next command
will then report an error even if there is no error in it.

Disabling error detection fixes the issue, and let the decoder continue
after an error. This patch is safe for backport into older kernels.

[PATCH 5.10 29/52] swiotlb: max mapping size takes min align mask into account

[Greg Kroah-Hartman]

From: Tianyu Lan <Tianyu.Lan@microsoft.com>

commit 82806744fd7dde603b64c151eeddaa4ee62193fd upstream.

swiotlb_find_slots() skips slots according to io tlb aligned mask
calculated from min aligned mask and original physical address
offset. This affects max mapping size. The mapping size can't
achieve the IO_TLB_SEGSIZE * IO_TLB_SIZE when original offset is
non-zero. This will cause system boot up failure in Hyper-V
Isolation VM where swiotlb force is enabled. Scsi layer use return
value of dma_max_mapping_size() to set max segment size and it
finally calls swiotlb_max_mapping_size(). Hyper-V storage driver
sets min align mask to 4k - 1. Scsi layer may pass 256k length of
request buffer with 0~4k offset and Hyper-V storage driver can't
get swiotlb bounce buffer via DMA API. Swiotlb_find_slots() can't
find 256k length bounce buffer with offset. Make swiotlb_max_mapping
_size() take min align mask into account.

[PATCH 5.10 30/52] scsi: hisi_sas: Revert "scsi: hisi_sas: Limit max hw sectors for v3 HW"

[Greg Kroah-Hartman]

From: Yu Kuai <yukuai3@huawei.com>

This reverts commit 24cd0b9bfdff126c066032b0d40ab0962d35e777.

1) commit 4e89dce72521 ("iommu/iova: Retry from last rb tree node if
iova search fails") tries to fix that iova allocation can fail while
there are still free space available. This is not backported to 5.10
stable.
2) commit fce54ed02757 ("scsi: hisi_sas: Limit max hw sectors for v3
HW") fix the performance regression introduced by 1), however, this
is just a temporary solution and will cause io performance regression
because it limit max io size to PAGE_SIZE * 32(128k for 4k page_size).
3) John Garry posted a patchset to fix the problem.
4) The temporary solution is reverted.

It's weird that the patch in 2) is backported to 5.10 stable alone,
while the right thing to do is to backport them all together.

[PATCH 5.10 36/52] soc: sunxi: sram: Fix probe function ordering issues

[Greg Kroah-Hartman]

From: Samuel Holland <samuel@sholland.org>

[ Upstream commit 49fad91a7b8941979c3e9a35f9894ac45bc5d3d6 ]

Errors from debugfs are intended to be non-fatal, and should not prevent
the driver from probing.

Since debugfs file creation is treated as infallible, move it below the
parts of the probe function that can fail. This prevents an error
elsewhere in the probe function from causing the file to leak. Do the
same for the call to of_platform_populate().

Finally, checkpatch suggests an octal literal for the file permissions.

Fixes: 4af34b572a85 ("drivers: soc: sunxi: Introduce SoC driver to map SRAMs")
Fixes: 5828729bebbb ("soc: sunxi: export a regmap for EMAC clock reg on A64")

[ Upstream commit 0a0342ede303fc420f3a388e1ae82da3ae8ff6bd ]

On probe of the ASoC component, the device is reset but the regcache is
retained. This means the regcache gets out of sync if the codec is
rebound to a sound card for a second time. Fix it by reinitializing the
regcache to defaults after the device is reset.

[PATCH 5.10 39/52] Revert "drm: bridge: analogix/dp: add panel prepare/unprepare in suspend/resume time"

[Greg Kroah-Hartman]

From: Brian Norris <briannorris@chromium.org>

[ Upstream commit cc62d98bd56d45de4531844ca23913a15136c05b ]

This reverts commit 211f276ed3d96e964d2d1106a198c7f4a4b3f4c0.

For quite some time, core DRM helpers already ensure that any relevant
connectors/CRTCs/etc. are disabled, as well as their associated
components (e.g., bridges) when suspending the system. Thus,
analogix_dp_bridge_{enable,disable}() already get called, which in turn
call drm_panel_{prepare,unprepare}(). This makes these drm_panel_*()
calls redundant.

Besides redundancy, there are a few problems with this handling:

(1) drm_panel_{prepare,unprepare}() are *not* reference-counted APIs and
are not in general designed to be handled by multiple callers --
although some panel drivers have a coarse 'prepared' flag that mitigates
some damage, at least. So at a minimum this is redundant and confusing,
but in some cases, this could be actively harmful.

(2) The error-handling is a bit non-standard. We ignored errors in
suspend(), but handled errors in resume(). And recently, people noticed
that the clk handling is unbalanced in error paths, and getting *that*
right is not actually trivial, given the current way errors are mostly
ignored.

(3) In the particular way analogix_dp_{suspend,resume}() get used (e.g.,
in rockchip_dp_*(), as a late/early callback), we don't necessarily have
a proper PM relationship between the DP/bridge device and the panel
device. So while the DP bridge gets resumed, the panel's parent device
(e.g., platform_device) may still be suspended, and so any prepare()
calls may fail.

So remove the superfluous, possibly-harmful suspend()/resume() handling
of panel state.

From: Peilin Ye <peilin.ye@bytedance.com>

[ Upstream commit a43206156263fbaf1f2b7f96257441f331e91bb7 ]

Currently usbnet_disconnect() unanchors and frees all deferred URBs
using usb_scuttle_anchored_urbs(), which does not free urb->context,
causing a memory leak as reported by syzbot.

Use a usb_get_from_anchor() while loop instead, similar to what we did
in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in
play_deferred").  Also free urb->sg.

'out' one, which skips the 'out_unlock' label, and thus doesn't unlock the

[PATCH 5.10 45/52] nvme: Fix IOC_PR_CLEAR and IOC_PR_RELEASE ioctls for nvme devices

[Greg Kroah-Hartman]

From: Michael Kelley <mikelley@microsoft.com>

[ Upstream commit c292a337d0e45a292c301e3cd51c35aa0ae91e95 ]

The IOC_PR_CLEAR and IOC_PR_RELEASE ioctls are
non-functional on NVMe devices because the nvme_pr_clear()
and nvme_pr_release() functions set the IEKEY field incorrectly.
The IEKEY field should be set only when the key is zero (i.e,
not specified).  The current code does it backwards.

Furthermore, the NVMe spec describes the persistent
reservation "clear" function as an option on the reservation
release command. The current implementation of nvme_pr_clear()
erroneously uses the reservation register command.

Fix these errors. Note that NVMe version 1.3 and later specify
that setting the IEKEY field will return an error of Invalid
Field in Command.  The fix will set IEKEY when the key is zero,
which is appropriate as these ioctls consider a zero key to
be "unspecified", and the intention of the spec change is
to require a valid key.

Tested on a version 1.4 PCI NVMe device in an Azure VM.

[PATCH 5.10 46/52] net: stmmac: power up/down serdes in stmmac_open/release

[Greg Kroah-Hartman]

From: Junxiao Chang <junxiao.chang@intel.com>

[ Upstream commit 49725ffc15fc4e9fae68c55b691fd25168cbe5c1 ]

This commit fixes DMA engine reset timeout issue in suspend/resume
with ADLink I-Pi SMARC Plus board which dmesg shows:
...
[   54.678271] PM: suspend exit
[   54.754066] intel-eth-pci 0000:00:1d.2 enp0s29f2: PHY [stmmac-3:01] driver [Maxlinear Ethernet GPY215B] (irq=POLL)

[   55.784115] intel-eth-pci 0000:00:1d.2 enp0s29f2: stmmac_open: Hw setup failed
...

The issue is related with serdes which impacts clock.  There is
serdes in ADLink I-Pi SMARC board ethernet controller. Please refer to
commit b9663b7ca6ff78 ("net: stmmac: Enable SERDES power up/down sequence")
for detial. When issue is reproduced, DMA engine clock is not ready
because serdes is not powered up.

To reproduce DMA engine reset timeout issue with hardware which has
serdes in GBE controller, install Ubuntu. In Ubuntu GUI, click
"Power Off/Log Out" -> "Suspend" menu, it disables network interface,
then goes to sleep mode. When it wakes up, it enables network
interface again. Stmmac driver is called in this way:

1. stmmac_release: Stop network interface. In this function, it
   disables DMA engine and network interface;
2. stmmac_suspend: It is called in kernel suspend flow. But because
   network interface has been disabled(netif_running(ndev) is
   false), it does nothing and returns directly;
3. System goes into S3 or S0ix state. Some time later, system is
   waken up by keyboard or mouse;
4. stmmac_resume: It does nothing because network interface has
   been disabled;
5. stmmac_open: It is called to enable network interace again. DMA
   engine is initialized in this API, but serdes is not power on so
   there will be DMA engine reset timeout issue.

Similarly, serdes powerdown should be added in stmmac_release.
Network interface might be disabled by cmd "ifconfig eth0 down",
DMA engine, phy and mac have been disabled in ndo_stop callback,
serdes should be powered down as well. It doesn't make sense that
serdes is on while other components have been turned off.

If ethernet interface is in enabled state(netif_running(ndev) is true)
before suspend/resume, the issue couldn't be reproduced  because serdes
could be powered up in stmmac_resume.

Because serdes_powerup is added in stmmac_open, it doesn't need to be
called in probe function.

There is no dedicate parent clock for QSPI so SET_RATE_PARENT flag
should not be used. For instance, the default parent clock for QSPI is
pll2_bus, which is also the parent clock for quite a few modules, such
as MMDC, once GPMI NAND set clock rate for EDO5 mode can cause system
hang due to pll2_bus rate changed.

[PATCH 5.10 49/52] clk: iproc: Do not rely on node name for correct PLL setup

[Greg Kroah-Hartman]

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit 1b24a132eba7a1c19475ba2510ec1c00af3ff914 ]

After commit 31fd9b79dc58 ("ARM: dts: BCM5301X: update CRU block
description") a warning from clk-iproc-pll.c was generated due to a
duplicate PLL name as well as the console stopped working. Upon closer
inspection it became clear that iproc_pll_clk_setup() used the Device
Tree node unit name as an unique identifier as well as a parent name to
parent all clocks under the PLL.

BCM5301X was the first platform on which that got noticed because of the
DT node unit name renaming but the same assumptions hold true for any
user of the iproc_pll_clk_setup() function.

The first 'clock-output-names' property is always guaranteed to be
unique as well as providing the actual desired PLL clock name, so we
utilize that to register the PLL and as a parent name of all children
clock.

I encountered some occasional crashes of poke_int3_handler() when
kprobes are set, while accessing desc->vec.

The text poke mechanism claims to have an RCU-like behavior, but it
does not appear that there is any quiescent state to ensure that
nobody holds reference to desc. As a result, the following race
appears to be possible, which can lead to memory corruption.

  CPU0					CPU1
  ----					----
  text_poke_bp_batch()
  -> smp_store_release(&bp_desc, &desc)

  [ notice that desc is on
    the stack			]

					poke_int3_handler()

					[ int3 might be kprobe's
					  so sync events are do not
					  help ]

					-> try_get_desc(descp=&bp_desc)
					   desc = __READ_ONCE(bp_desc)

					   if (!desc) [false, success]
  WRITE_ONCE(bp_desc, NULL);
  atomic_dec_and_test(&desc.refs)

  [ success, desc space on the stack
    is being reused and might have
    non-zero value. ]
					arch_atomic_inc_not_zero(&desc->refs)

					[ might succeed since desc points to
					  stack memory that was freed and might
					  be reused. ]

Fix this issue with small backportable patch. Instead of trying to
make RCU-like behavior for bp_desc, just eliminate the unnecessary
level of indirection of bp_desc, and hold the whole descriptor as a
global.  Anyhow, there is only a single descriptor at any given
moment.

[PATCH 5.10 52/52] ALSA: hda/hdmi: fix warning about PCM count when used with SOF

[Greg Kroah-Hartman]

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

commit c74193787b2f683751a67603fb5f15c7584f355f upstream.

With commit 13046370c4d1 ("ALSA: hda/hdmi: let new platforms assign the
pcm slot dynamically"), old behaviour to consider the HDA pin number,
when choosing PCM to assign, was dropped.

Build on this change and limit the number of PCMs created to number of
converters (= maximum number of concurrent display/receivers) when
"mst_no_extra_pcms" and "dyn_pcm_no_legacy" quirks are both set.

Fix the check in hdmi_find_pcm_slot() to ensure only spec->pcm_used
entries are considered in the search. Elsewhere in the driver
spec->pcm_used is already checked properly.

Doing this avoids following warning at SOF driver probe for multiple
machine drivers:

[  112.425297] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no
PCM in topology for HDMI converter 4
[  112.425298] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no
PCM in topology for HDMI converter 5
[  112.425299] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no
PCM in topology for HDMI converter 6

I don't believe you got the error handling right.

Ok, so serdes is powered up here.

But this goes to init_error, and exits w/o powering serdes down. Error
handling needs to be fixed AFAICT.
