commit d96f04d347e4011977abdbb4da5d8f303ebd26f8 upstream.
It has been observed that once per 300-1300 port openings the first
transmitted byte is being corrupted on AM3352 ("v" written to FIFO appeared
as "e" on the wire). It only happened if single byte has been transmitted
right after port open, which means, DMA is not used for this transfer and
the corruption never happened afterwards.
Therefore I've carefully re-read the MDR1 errata (link below), which says
"when accessing the MDR1 registers that causes a dummy under-run condition
that will freeze the UART in IrDA transmission. In UART mode, this may
corrupt the transferred data". Strictly speaking,
omap_8250_mdr1_errataset() performs a read access and if the value is the
same as should be written, exits without errata-recommended FIFO reset.
A brief check of the serial_omap_mdr1_errataset() from the competing
omap-serial driver showed it has no read access of MDR1. After removing the
read access from omap_8250_mdr1_errataset() the data corruption never
happened any more.

commit 862ee699fefe1e6d6f2c1518395f0b999b8beb15 upstream.
The console part of sisusbvga is broken vs. printk(). It uses in_atomic()
to detect contexts in which it cannot sleep despite the big fat comment in
preempt.h which says: Do not use in_atomic() in driver code.
in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which
means that spin/rw_lock held regions are not detected by it.
There is no way to make this work by handing context information through to
the driver and this only can be solved once the core printk infrastructure
supports sleepable console drivers.
Make it depend on BROKEN for now.

commit 8010622c86ca5bb44bc98492f5968726fc7c7a21 upstream.
UAS does not share the pessimistic assumption storage is making that
devices cannot deal with WRITE_SAME. A few devices supported by UAS,
are reported to not deal well with WRITE_SAME. Those need a quirk.
Add it to the device that needs it.

commit 5a8e3229ac27956bdcc25b2709e5d196d109a27a upstream.
Intel Maple Ridge is successor of Titan Ridge Thunderbolt controller. As
Titan Ridge this one also includes xHCI host controller. In order to
safe energy we should put it to low power state by default when idle.
For this reason allow host runtime PM for Maple Ridge.

commit c4d1ca05b8e68a4b5a3c4455cb6ec25b3df6d9dd upstream.
The xHCI controller on Alpine Ridge LP keeps the whole Thunderbolt
controller awake if the host controller is not allowed to sleep.
This is the case even if no USB devices are connected to the host.
Add the Intel Alpine Ridge LP product-id to the list of product-ids
for which we allow runtime PM by default.

commit c1373f10479b624fb6dba0805d673e860f1b421d upstream.
If a USB2 device wakeup is not enabled/supported the link state may
still be in U0 in xhci_bus_suspend(), where it's then manually put
to suspended U3 state.
Just as with selective suspend the device needs time to enter U3
suspend before continuing with further suspend operations
(e.g. system suspend), otherwise we may enter system suspend with link
state in U0.

[ Upstream commit 007ab5345545aba2f9cbe4c096cc35d2fd3275ac ]
Don't try to adjust XFRM support flags if the bond device isn't yet
registered. Bad things can currently happen when netdev_change_features()
is called without having wanted_features fully filled in yet. This code
runs both on post-module-load mode changes, as well as at module init
time, and when run at module init time, it is before register_netdevice()
has been called and filled in wanted_features. The empty wanted_features
led to features also getting emptied out, which was definitely not the
intended behavior, so prevent that from happening.
Originally, I'd hoped to stop adjusting wanted_features at all in the
bonding driver, as it's documented as being something only the network
core should touch, but we actually do need to do this to properly update
both the features and wanted_features fields when changing the bond type,
or we get to a situation where ethtool sees:
esp-hw-offload: off [requested on]
I do think we should be using netdev_update_features instead of
netdev_change_features here though, so we only send notifiers when the
features actually changed.

[ Upstream commit 4ec236c7c51f89abb0224a4da4a6b77f9beb6600 ]
When do suspend/resume test, there have WARN_ON() log dump from
stmmac_xmit() funciton, the code logic:
entry = tx_q->cur_tx;
first_entry = entry;
WARN_ON(tx_q->tx_skbuff[first_entry]);
In normal case, tx_q->tx_skbuff[txq->cur_tx] should be NULL because
the skb should be handled and freed in stmmac_tx_clean().
But stmmac_resume() reset queue parameters like below, skb buffers
may not be freed.
tx_q->cur_tx = 0;
tx_q->dirty_tx = 0;
So free tx skb buffer in stmmac_resume() to avoid warning and
memory leak.

[ Upstream commit 82ca4c922b8992013a238d65cf4e60cc33e12f36 ]
The m250_sel mux clock uses bit 4 in the PRG_ETH0 register. Fix this by
shifting the PRG_ETH0_CLK_M250_SEL_MASK accordingly as the "mask" in
struct clk_mux expects the mask relative to the "shift" field in the
same struct.
While here, get rid of the PRG_ETH0_CLK_M250_SEL_SHIFT macro and use
__ffs() to determine it from the existing PRG_ETH0_CLK_M250_SEL_MASK
macro.

[ Upstream commit 61f54de2e9194f01874d5eda12037b0978e77519 ]
hclge_dbg_reg_info[] is defined as an array of packed structure
accidentally. However, this array contains pointers, which are
no longer aligned naturally, and cannot be relocated on PPC64.
Hence, when compile-testing this driver on PPC64 with
CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be
some warnings.
Since each field in structure hclge_qos_pri_map_cmd and
hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary
for these two structures as well, so remove the pragma packed in
hclge_debugfs.h to fix this issue, and this increases
hclge_dbg_reg_info[] by 4 bytes per entry.

[ Upstream commit edd2410b165e2ef00b2264ae362edf7441ca929c ]
The current assumption is that the felix DSA driver has flooding knobs
per traffic class, while ocelot switchdev has a single flooding knob.
This was correct for felix VSC9959 and ocelot VSC7514, but with the
introduction of seville VSC9953, we see a switch driven by felix.c which
has a single flooding knob.
So it is clear that we must do what should have been done from the
beginning, which is not to overwrite the configuration done by ocelot.c
in felix, but instead to teach the common ocelot library about the
differences in our switches, and set up the flooding PGIDs centrally.
The effect that the bogus iteration through FELIX_NUM_TC has upon
seville is quite dramatic. ANA_FLOODING is located at 0x00b548, and
ANA_FLOODING_IPMC is located at 0x00b54c. So the bogus iteration will
actually overwrite ANA_FLOODING_IPMC when attempting to write
ANA_FLOODING[1]. There is no ANA_FLOODING[1] in sevile, just ANA_FLOODING.
And when ANA_FLOODING_IPMC is overwritten with a bogus value, the effect
is that ANA_FLOODING_IPMC gets the value of 0x0003CF7D:
MC6_DATA = 61,
MC6_CTRL = 61,
MC4_DATA = 60,
MC4_CTRL = 0.
Because MC4_CTRL is zero, this means that IPv4 multicast control packets
are not flooded, but dropped. An invalid configuration, and this is how
the issue was actually spotted.

commit 0fe8bf4d3edce7aad6c14b9d5d92ff54dc19f0ba upstream.
We currently presume that the engine reset is successful, cancelling the
expired preemption timer in the process. However, engine resets can
fail, leaving the timeout still pending and we will then respond to the
timeout again next time the tasklet fires. What we want is for the
failed engine reset to be promoted to a full device reset, which is
kicked by the heartbeat once the engine stops processing events.

commit f6cbe49be65ed800863ac5ba695555057363f9c2 upstream.
This patch fixes the slice count computation algorithm
for calculating the slice count based on Peak pixel rate
and the max slice width allowed on the DSC engines.
We need to ensure slice count > min slice count req
as per DP spec based on peak pixel rate and that it is
greater than min slice count based on the max slice width
advertised by DPCD. So use max of these two.
In the prev patch we were using min of these 2 causing it
to violate the max slice width limitation causing a blank
screen on 8K@60.

commit 0e124e19ce52d20b28ee9f1d5cdb22e2106bfd29 upstream.
In the course of discovering and closing many races with context closure
and execbuf submission, since commit 61231f6bd056 ("drm/i915/gem: Check
that the context wasn't closed during setup") we started checking that
the context was not closed by another userspace thread during the execbuf
ioctl. In doing so we cancelled the inflight request (by telling it to be
skipped), but kept reporting success since we do submit a request, albeit
one that doesn't execute. As the error is known before we return from the
ioctl, we can report the error we detect immediately, rather than leave
it on the fence status. With the immediate propagation of the error, it
is easier for userspace to handle.

commit 47a0001436352c9853d72bf2071e85b316d688a2 upstream.
Debounce filter setting should be independent from IRQ type setting
because according to the ACPI specs, there are separate arguments for
specifying debounce timeout and IRQ type in GpioIo() and GpioInt().
Together with commit 06abe8291bc31839950f7d0362d9979edc88a666
("pinctrl: amd: fix incorrect way to disable debounce filter") and
Andy's patch "gpiolib: acpi: Take into account debounce settings" [1],
this will fix broken touchpads for laptops whose BIOS set the
debounce timeout to a relatively large value. For example, the BIOS
of Lenovo AMD gaming laptops including Legion-5 15ARH05 (R7000),
Legion-5P (R7000P) and IdeaPad Gaming 3 15ARH05, set the debounce
timeout to 124.8ms. This led to the kernel receiving only ~7 HID
reports per second from the Synaptics touchpad
(MSFT0001:00 06CB:7F28).
Existing touchpads like [2][3] are not troubled by this bug because
the debounce timeout has been set to 0 by the BIOS before enabling
the debounce filter in setting IRQ type.

[ 119.872358] mmc0: running CQE recovery
From these logs, we found TDL base was back to the default value.
After suspend, the mmc host is powered off by HW, and bring CQE register
to the default value, so we add system suspend/resume interface, then bring
CQE to deactivated state before suspend, it will be enabled by CQE first
request after resume.

commit 45ba1c0ba3e589ad3ef0d0603c822eb27ea16563 upstream.
Starting with firmware version 10 the GET/SET_HDMI_VERSION message
was removed and GET/SET_AUTO_POWER_ON was added.
The removal of GET/SET_HDMI_VERSION caused the probe of the
Pulse-Eight to fail. Add a version check to handle this gracefully.
Also show (but do not set) the Auto Power On value.

commit 024e01dead12c2b9fbe31216f2099401ebb78a4a upstream.
Commit 601282d65b96 ("media: pulse8-cec: use adap_free callback") used
the adap_free callback to clean up on disconnect. What I forgot was that
in the probe it will call cec_delete_adapter() followed by kfree(pulse8)
if an error occurs. But by using the adap_free callback,
cec_delete_adapter() is already freeing the pulse8 struct.
This wasn't noticed since normally the probe works fine, but Pulse-Eight
published a new firmware version that caused a probe error, so now it
hits this bug. This affects firmware version 12, but probably any
version >= 10.
Commit aa9eda76129c ("media: pulse8-cec: close serio in disconnect, not
adap_free") made this worse by adding the line 'pulse8->serio = NULL'
right after the call to cec_unregister_adapter in the disconnect()
function. Unfortunately, cec_unregister_adapter will typically call
cec_delete_adapter (unless a filehandle to the cec device is still
open), which frees the pulse8 struct. So now it will also crash on a
simple unplug of the Pulse-Eight device.
With this fix both the unplug issue and a probe() error situation are
handled correctly again.
It will still fail to probe() with a v12 firmware, that's something
to look at separately.
