Pull regulator fix from Mark Brown:
"The recently added regulator-uv-survival-time-ms property was renamed
during the review of the series that added it, but unfortunately only
in the DT binding and not in the code that parses the binding.
This brings the code in line with the binding, if someone started
using the original name we can add compat support for it but there's
nothing upstream yet and it's a very niche feature so hopefully not"

If a PCIe port only supports a single speed, enabling bandwidth control
is pointless: There's no need to monitor autonomous speed changes, nor
can the speed be changed.
Not enabling it saves a small amount of memory and compute resources,
but also fixes a boot hang reported by Niklas: It occurs when enabling
bandwidth control on Downstream Ports of Intel JHL7540 "Titan Ridge 2018"
Thunderbolt controllers. The ports only support 2.5 GT/s in accordance
with USB4 v2 sec 11.2.1, so the present commit works around the issue.
PCIe r6.2 sec 8.2.1 prescribes that:
"A device must support 2.5 GT/s and is not permitted to skip support
for any data rates between 2.5 GT/s and the highest supported rate."
Consequently, bandwidth control is currently only disabled if a port
doesn't support higher speeds than 2.5 GT/s. However the Implementation
Note in PCIe r6.2 sec 7.5.3.18 cautions:
"It is strongly encouraged that software primarily utilize the
Supported Link Speeds Vector instead of the Max Link Speed field,
so that software can determine the exact set of supported speeds on
current and future hardware. This can avoid software being confused
if a future specification defines Links that do not require support
for all slower speeds."
In other words, future revisions of the PCIe Base Spec may allow gaps
in the Supported Link Speeds Vector. To be future-proof, don't just
check whether speeds above 2.5 GT/s are supported, but rather check
whether *more than one* speed is supported.

The Supported Link Speeds Vector in the Link Capabilities 2 Register
indicates the *supported* link speeds. The Max Link Speed field in the
Link Capabilities Register indicates the *maximum* of those speeds.
pcie_get_supported_speeds() neglects to honor the Max Link Speed field and
will thus incorrectly deem higher speeds as supported. Fix it.
One user-visible issue addressed here is an incorrect value in the sysfs
attribute "max_link_speed".
But the main motivation is a boot hang reported by Niklas: Intel JHL7540
"Titan Ridge 2018" Thunderbolt controllers supports 2.5-8 GT/s speeds,
but indicate 2.5 GT/s as maximum. Ilpo recalls seeing this on more
devices. It can be explained by the controller's Downstream Ports
supporting 8 GT/s if an Endpoint is attached, but limiting to 2.5 GT/s
if the port interfaces to a PCIe Adapter, in accordance with USB4 v2
sec 11.2.1:
"This section defines the functionality of an Internal PCIe Port that
interfaces to a PCIe Adapter. [...]
The Logical sub-block shall update the PCIe configuration registers
with the following characteristics: [...]
Max Link Speed field in the Link Capabilities Register set to 0001b
(data rate of 2.5 GT/s only).
Note: These settings do not represent actual throughput. Throughput
is implementation specific and based on the USB4 Fabric performance."
The present commit is not sufficient on its own to fix Niklas' boot hang,
but it is a prerequisite: A subsequent commit will fix the boot hang by
enabling bandwidth control only if more than one speed is supported.
The GENMASK() macro used herein specifies 0 as lowest bit, even though
the Supported Link Speeds Vector ends at bit 1. This is done on purpose
to avoid a GENMASK(0, 1) macro if Max Link Speed is zero. That macro
would be invalid as the lowest bit is greater than the highest bit.
Ilpo has witnessed a zero Max Link Speed on Root Complex Integrated
Endpoints in particular, so it does occur in practice. (The Link
Capabilities Register is optional on RCiEPs per PCIe r6.2 sec 7.5.3.)

The regulator bindings don't document regulator-uv-survival-time-ms, but
the more descriptive regulator-uv-less-critical-window-ms instead.
Looking back at v3[1] and v4[2] of the series adding the support,
the property was indeed renamed between these patch series, but
unfortunately the rename only made it into the DT bindings with the
driver code still using the old name.
Let's therefore rename the property in the driver code to follow suit.
This will break backwards compatibility, but there are no upstream
device trees using the property and we never documented the old name
of the property anyway. ¯\_(ツ)_/¯"

Setting backing device is done before ZRAM initialization. If we set the
backing device, then remove the ZRAM module without initializing the
device, the backing device reference will be leaked and the device will be
hold forever.

Patch series "zram: fix backing device setup issue", v2.
This series fixes two bugs of backing device setting:
- ZRAM should reject using a zero sized (or the uninitialized ZRAM
device itself) as the backing device.
- Fix backing device leaking when removing a uninitialized ZRAM
device.
This patch (of 2):
Setting a zero sized block device as backing device is pointless, and one
can easily create a recursive loop by setting the uninitialized ZRAM
device itself as its own backing device by (zram0 is uninitialized):
echo /dev/zram0 > /sys/block/zram0/backing_dev
It's definitely a wrong config, and the module will pin itself, kernel
should refuse doing so in the first place.
By refusing to use zero sized device we avoided misuse cases including
this one above.

gcc runs into undefined behavior at the end of the three led_polarity_set()
callback functions if it were called with a zero 'modes' argument and it
just ends the function there without returning from it.
This gets flagged by 'objtool' as a function that continues on
to the next one:
drivers/net/phy/aquantia/aquantia_leds.o: warning: objtool: aqr_phy_led_polarity_set+0xf: can't find jump dest instruction at .text+0x5d9
drivers/net/phy/intel-xway.o: warning: objtool: xway_gphy_led_polarity_set() falls through to next function xway_gphy_config_init()
drivers/net/phy/mxl-gpy.o: warning: objtool: gpy_led_polarity_set() falls through to next function gpy_led_hw_control_get()
There is no point to micro-optimize the behavior here to save a single-digit
number of bytes in the kernel, so just change this to a "return -EINVAL"
as we do when any unexpected bits are set.

There are 2 issues with bq24296_set_otg_vbus():
1. When writing the OTG_CONFIG bit it uses POC_CHG_CONFIG_SHIFT which
should be POC_OTG_CONFIG_SHIFT.
2. When turning the regulator off it never turns charging back on. Note
this must be done through bq24190_charger_set_charge_type(), to ensure
that the charge_type property value of none/trickle/fast is honored.
Resolve both issues to fix BQ24296 Vbus regulator support not working.

Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()")
accessing job->base.sched can produce unexpected results as the initialisation
of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the
memset.
This commit fixes an issue when a CS would fail validation and would
be rejected after job->num_ibs is incremented. In this case,
amdgpu_ib_free(ring->adev, ...) will be called, which would crash the
machine because the ring value is bogus.
To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this
because the device is actually not used in this function.
The next commit will remove the ring argument completely.

The current implementation does not work if the thermal zone is
interrupt driven only.
The boundaries are not correctly checked and computed as it happens
only when the temperature is increasing or decreasing.
The problem arises because the routine to detect when we cross a
threshold is correlated with the computation of the boundaries. We
assume we have to recompute the boundaries when a threshold is crossed
but actually we should do that even if the it is not the case.
Mixing the boundaries computation and the threshold detection for the
sake of optimizing the routine is much more complex as it appears
intuitively and prone to errors.
This fix separates the boundaries computation and the threshold
crossing detection into different routines. The result is a code much
more simple to understand, thus easier to maintain.
The drawback is we browse the thresholds list several time but we can
consider that as neglictible because that happens when the temperature
is updated. There are certainly some aeras to improve in the
temperature update routine but it would be not adequate as this change
aims to fix the thresholds for v6.13.

The interrupt line of PCI devices is interpreted as edge-triggered,
however the interrupt signal of the m_can controller integrated in Intel
Elkhart Lake CPUs appears to be generated level-triggered.
Consider the following sequence of events:
- IR register is read, interrupt X is set
- A new interrupt Y is triggered in the m_can controller
- IR register is written to acknowledge interrupt X. Y remains set in IR
As at no point in this sequence no interrupt flag is set in IR, the
m_can interrupt line will never become deasserted, and no edge will ever
be observed to trigger another run of the ISR. This was observed to
result in the TX queue of the EHL m_can to get stuck under high load,
because frames were queued to the hardware in m_can_start_xmit(), but
m_can_finish_tx() was never run to account for their successful
transmission.
On an Elkhart Lake based board with the two CAN interfaces connected to
each other, the following script can reproduce the issue:
ip link set can0 up type can bitrate 1000000
ip link set can1 up type can bitrate 1000000
cangen can0 -g 2 -I 000 -L 8 &
cangen can0 -g 2 -I 001 -L 8 &
cangen can0 -g 2 -I 002 -L 8 &
cangen can0 -g 2 -I 003 -L 8 &
cangen can0 -g 2 -I 004 -L 8 &
cangen can0 -g 2 -I 005 -L 8 &
cangen can0 -g 2 -I 006 -L 8 &
cangen can0 -g 2 -I 007 -L 8 &
cangen can1 -g 2 -I 100 -L 8 &
cangen can1 -g 2 -I 101 -L 8 &
cangen can1 -g 2 -I 102 -L 8 &
cangen can1 -g 2 -I 103 -L 8 &
cangen can1 -g 2 -I 104 -L 8 &
cangen can1 -g 2 -I 105 -L 8 &
cangen can1 -g 2 -I 106 -L 8 &
cangen can1 -g 2 -I 107 -L 8 &
stress-ng --matrix 0 &
To fix the issue, repeatedly read and acknowledge interrupts at the
start of the ISR until no interrupt flags are set, so the next incoming
interrupt will also result in an edge on the interrupt line.
While we have received a report that even with this patch, the TX queue
can become stuck under certain (currently unknown) circumstances on the
Elkhart Lake, this patch completely fixes the issue with the above
reproducer, and it is unclear whether the remaining issue has a similar
cause at all.

While an m_can controller usually already has the init flag from a
hardware reset, no such reset happens on the integrated m_can_pci of the
Intel Elkhart Lake. If the CAN controller is found in an active state,
m_can_dev_setup() would fail because m_can_niso_supported() calls
m_can_cccr_update_bits(), which refuses to modify any other configuration
bits when CCCR_INIT is not set.
To avoid this issue, set CCCR_INIT before attempting to modify any other
configuration flags.

There is a race condition between exiting wb_on_itr and completion write
backs. For example, we are in wb_on_itr mode and a Tx completion is
generated by HW, ready to be written back, as we are re-enabling
interrupts:
HW SW
| |
| | idpf_tx_splitq_clean_all
| | napi_complete_done
| |
| tx_completion_wb | idpf_vport_intr_update_itr_ena_irq
That tx_completion_wb happens before the vector is fully re-enabled.
Continuing with this example, it is a UDP stream and the
tx_completion_wb is the last one in the flow (there are no rx packets).
Because the HW generated the completion before the interrupt is fully
enabled, the HW will not fire the interrupt once the timer expires and
the write back will not happen. NAPI poll won't be called. We have
indicated we're back in interrupt mode but nothing else will trigger the
interrupt. Therefore, the completion goes unprocessed, triggering a Tx
timeout.
To mitigate this, fire a SW triggered interrupt upon exiting wb_on_itr.
This interrupt will catch the rogue completion and avoid the timeout.
Add logic to set the appropriate bits in the vector's dyn_ctl register.
