+Subject: ALSA: usb-audio: Re-add ScratchAmp quirk entries
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit 03898691d42e0170e7d00f07cbe21ce0e9f3a8fa ]
+
+At the code refactoring of USB-audio quirk handling, I assumed that
+the quirk entries of Stanton ScratchAmp devices were only about the
+device name, and moved them completely into the rename table.
+But it seems that the device requires the quirk entry so that it's
+probed by the driver itself.
+
+This re-adds back the quirk entries of ScratchAmp, but in a
+minimalistic manner.
+
+Fixes: 5436f59bc5bc ("ALSA: usb-audio: Move device rename and profile quirks to an internal table")

+
+From: Mark Rutland <mark.rutland@arm.com>
+
+[ Upstream commit ebfc726eae3f31bdb5fae1bbd74ef235d71046ca ]
+
+Upcoming errata workarounds will need to use SB from C code. Restore the
+spec_bar() macro so that we can use SB.
+
+This is effectively a revert of commit:

+Subject: arm64: errata: Add workaround for Arm errata 3194386 and 3312417
+
+From: Mark Rutland <mark.rutland@arm.com>
+
+[ Upstream commit 7187bb7d0b5c7dfa18ca82e9e5c75e13861b1d88 ]
+
+Cortex-X4 and Neoverse-V3 suffer from errata whereby an MSR to the SSBS
+special-purpose register does not affect subsequent speculative
+instructions, permitting speculative store bypassing for a window of
+time. This is described in their Software Developer Errata Notice (SDEN)
+documents:
+
+* Cortex-X4 SDEN v8.0, erratum 3194386:
+ https://developer.arm.com/documentation/SDEN-2432808/0800/
+
+* Neoverse-V3 SDEN v6.0, erratum 3312417:
+ https://developer.arm.com/documentation/SDEN-2891958/0600/
+
+To workaround these errata, it is necessary to place a speculation
+barrier (SB) after MSR to the SSBS special-purpose register. This patch
+adds the requisite SB after writes to SSBS within the kernel, and hides
+the presence of SSBS from EL0 such that userspace software which cares
+about SSBS will manipulate this via prctl(PR_GET_SPECULATION_CTRL, ...).

+Subject: arm64: errata: Expand speculative SSBS workaround (again)
+
+From: Mark Rutland <mark.rutland@arm.com>
+
+[ Upstream commit b0672bbe133ebb6f7be21fce1d742d52f25bcdc7 ]
+
+A number of Arm Ltd CPUs suffer from errata whereby an MSR to the SSBS
+special-purpose register does not affect subsequent speculative
+instructions, permitting speculative store bypassing for a window of
+time.
+
+We worked around this for a number of CPUs in commits:
+
+* 7187bb7d0b5c7dfa ("arm64: errata: Add workaround for Arm errata 3194386 and 3312417")
+* 75b3c43eab594bfb ("arm64: errata: Expand speculative SSBS workaround")
+
+Since then, similar errata have been published for a number of other Arm
+Ltd CPUs, for which the same mitigation is sufficient. This is described
+in their respective Software Developer Errata Notice (SDEN) documents:
+
+* Cortex-A76 (MP052) SDEN v31.0, erratum 3324349
+ https://developer.arm.com/documentation/SDEN-885749/3100/
+
+* Cortex-A77 (MP074) SDEN v19.0, erratum 3324348
+ https://developer.arm.com/documentation/SDEN-1152370/1900/
+
+* Cortex-A78 (MP102) SDEN v21.0, erratum 3324344
+ https://developer.arm.com/documentation/SDEN-1401784/2100/
+
+* Cortex-A78C (MP138) SDEN v16.0, erratum 3324346
+ https://developer.arm.com/documentation/SDEN-1707916/1600/
+
+* Cortex-A78C (MP154) SDEN v10.0, erratum 3324347
+ https://developer.arm.com/documentation/SDEN-2004089/1000/
+
+* Cortex-A725 (MP190) SDEN v5.0, erratum 3456106
+ https://developer.arm.com/documentation/SDEN-2832921/0500/
+
+* Cortex-X1 (MP077) SDEN v21.0, erratum 3324344
+ https://developer.arm.com/documentation/SDEN-1401782/2100/
+
+* Cortex-X1C (MP136) SDEN v16.0, erratum 3324346
+ https://developer.arm.com/documentation/SDEN-1707914/1600/
+
+* Neoverse-N1 (MP050) SDEN v32.0, erratum 3324349
+ https://developer.arm.com/documentation/SDEN-885747/3200/
+
+* Neoverse-V1 (MP076) SDEN v19.0, erratum 3324341
+ https://developer.arm.com/documentation/SDEN-1401781/1900/
+
+Note that due to the manner in which Arm develops IP and tracks errata,
+some CPUs share a common erratum number and some CPUs have multiple
+erratum numbers for the same HW issue.
+
+On parts without SB, it is necessary to use ISB for the workaround. The
+spec_bar() macro used in the mitigation will expand to a "DSB SY; ISB"
+sequence in this case, which is sufficient on all affected parts.
+
+Enable the existing mitigation by adding the relevant MIDRs to
+erratum_spec_ssbs_list. The list is sorted alphanumerically (involving
+moving Neoverse-V3 after Neoverse-V2) so that this is easy to audit and
+potentially extend again in future. The Kconfig text is also updated to
+clarify the set of affected parts and the mitigation.

+Subject: arm64: errata: Expand speculative SSBS workaround
+
+From: Mark Rutland <mark.rutland@arm.com>
+
+[ Upstream commit 75b3c43eab594bfbd8184ec8ee1a6b820950819a ]
+
+A number of Arm Ltd CPUs suffer from errata whereby an MSR to the SSBS
+special-purpose register does not affect subsequent speculative
+instructions, permitting speculative store bypassing for a window of
+time.
+
+We worked around this for Cortex-X4 and Neoverse-V3, in commit:
+
+ 7187bb7d0b5c7dfa ("arm64: errata: Add workaround for Arm errata 3194386 and 3312417")
+
+... as per their Software Developer Errata Notice (SDEN) documents:
+
+* Cortex-X4 SDEN v8.0, erratum 3194386:
+ https://developer.arm.com/documentation/SDEN-2432808/0800/
+
+* Neoverse-V3 SDEN v6.0, erratum 3312417:
+ https://developer.arm.com/documentation/SDEN-2891958/0600/
+
+Since then, similar errata have been published for a number of other Arm Ltd
+CPUs, for which the mitigation is the same. This is described in their
+respective SDEN documents:
+
+* Cortex-A710 SDEN v19.0, errataum 3324338
+ https://developer.arm.com/documentation/SDEN-1775101/1900/?lang=en
+
+* Cortex-A720 SDEN v11.0, erratum 3456091
+ https://developer.arm.com/documentation/SDEN-2439421/1100/?lang=en
+
+* Cortex-X2 SDEN v19.0, erratum 3324338
+ https://developer.arm.com/documentation/SDEN-1775100/1900/?lang=en
+
+* Cortex-X3 SDEN v14.0, erratum 3324335
+ https://developer.arm.com/documentation/SDEN-2055130/1400/?lang=en
+
+* Cortex-X925 SDEN v8.0, erratum 3324334
+ https://developer.arm.com/documentation/109108/800/?lang=en
+
+* Neoverse-N2 SDEN v17.0, erratum 3324339
+ https://developer.arm.com/documentation/SDEN-1982442/1700/?lang=en
+
+* Neoverse-V2 SDEN v9.0, erratum 3324336
+ https://developer.arm.com/documentation/SDEN-2332927/900/?lang=en
+
+Note that due to shared design lineage, some CPUs share the same erratum
+number.
+
+Add these to the existing mitigation under CONFIG_ARM64_ERRATUM_3194386.
+As listing all of the erratum IDs in the runtime description would be
+unwieldy, this is reduced to:
+
+ "SSBS not fully self-synchronizing"
+
+... matching the description of the errata in all of the SDENs.

+Subject: arm64: errata: Unify speculative SSBS errata logic
+
+From: Mark Rutland <mark.rutland@arm.com>
+
+[ Upstream commit ec768766608092087dfb5c1fc45a16a6f524dee2 ]
+
+Cortex-X4 erratum 3194386 and Neoverse-V3 erratum 3312417 are identical,
+with duplicate Kconfig text and some unsightly ifdeffery. While we try
+to share code behind CONFIG_ARM64_WORKAROUND_SPECULATIVE_SSBS, having
+separate options results in a fair amount of boilerplate code, and this
+will only get worse as we expand the set of affected CPUs.
+
+To reduce this boilerplate, unify the two behind a common Kconfig
+option. This removes the duplicate text and Kconfig logic, and removes
+the need for the intermediate ARM64_WORKAROUND_SPECULATIVE_SSBS option.
+The set of affected CPUs is described as a list so that this can easily
+be extended.
+
+I've used ARM64_ERRATUM_3194386 (matching the Neoverse-V3 erratum ID) as
+the common option, matching the way we use ARM64_ERRATUM_1319367 to
+cover Cortex-A57 erratum 1319537 and Cortex-A72 erratum 1319367.

+Subject: ASoC: codecs: wcd938x-sdw: Correct Soundwire ports mask
+
+From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
+
+[ Upstream commit 3f6fb03dae9c7dfba7670858d29e03c8faaa89fe ]
+
+Device has up to WCD938X_MAX_SWR_PORTS number of ports and the array
+assigned to prop.src_dpn_prop and prop.sink_dpn_prop has
+0..WCD938X_MAX_SWR_PORTS-1 elements. On the other hand, GENMASK(high,
+low) creates an inclusive mask between <high, low>, so we need the mask
+from 0 up to WCD938X_MAX_SWR_PORTS-1.
+
+Theoretically, too wide mask could cause an out of bounds read in
+sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy
+driver, e.g. adding incorrect number of ports via
+sdw_stream_add_slave().

+Subject: ASoC: meson: axg-fifo: fix irq scheduling issue with PREEMPT_RT
+
+From: Jerome Brunet <jbrunet@baylibre.com>
+
+[ Upstream commit 5003d0ce5c7da3a02c0aff771f516f99731e7390 ]
+
+With PREEMPT_RT enabled a spinlock_t becomes a sleeping lock.
+
+This is usually not a problem with spinlocks used in IRQ context since
+IRQ handlers get threaded. However, if IRQF_ONESHOT is set, the primary
+handler won't be force-threaded and runs always in hardirq context. This is
+a problem because spinlock_t requires a preemptible context on PREEMPT_RT.
+
+In this particular instance, regmap mmio uses spinlock_t to protect the
+register access and IRQF_ONESHOT is set on the IRQ. In this case, it is
+actually better to do everything in threaded handler and it solves the
+problem with PREEMPT_RT.

+
+[ Upstream commit 14d02fbadb5dc1cdf66078ef8430dd1cd22bfd53 ]
+
+The I2C Master Hub is a stripped down version of the GENI Serial Engine
+QUP Wrapper Controller but only supporting I2C serial engines without
+DMA support.
+
+Those I2C serial engines variants have some requirements:
+- a separate "core" clock
+- doesn't support DMA, thus no memory interconnect path
+- fixed FIFO size not discoverable in the HW_PARAM_0 register
+
+Add a desc struct specifying all those requirements which will be used in
+a next change when adding the I2C Master Hub serial engine compatible.

+Subject: i2c: smbus: Improve handling of stuck alerts
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 37c526f00bc1c4f847fc800085f8f009d2e11be6 ]
+
+The following messages were observed while testing alert functionality
+on systems with multiple I2C devices on a single bus if alert was active
+on more than one chip.
+
+smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0
+smbus_alert 3-000c: no driver alert()!
+
+and:
+
+smbus_alert 3-000c: SMBALERT# from dev 0x28, flag 0
+
+Once it starts, this message repeats forever at high rate. There is no
+device at any of the reported addresses.
+
+Analysis shows that this is seen if multiple devices have the alert pin
+active. Apparently some devices do not support SMBus arbitration correctly.
+They keep sending address bits after detecting an address collision and
+handle the collision not at all or too late.
+Specifically, address 0x0c is seen with ADT7461A at address 0x4c and
+ADM1021 at address 0x18 if alert is active on both chips. Address 0x28 is
+seen with ADT7483 at address 0x2a and ADT7461 at address 0x4c if alert is
+active on both chips.
+
+Once the system is in bad state (alert is set by more than one chip),
+it often only recovers by power cycling.
+
+To reduce the impact of this problem, abort the endless loop in
+smbus_alert() if the same address is read more than once and not
+handled by a driver.

+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit f6c29f710c1ff2590109f83be3e212b86c01e0f3 ]
+
+If a SMBus alert is received and the originating device is not found,
+the reason may be that the address reported on the SMBus alert address
+is corrupted, for example because multiple devices asserted alert and
+do not correctly implement SMBus arbitration.
+
+If this happens, call alert handlers on all devices connected to the
+given I2C bus, in the hope that this cleans up the situation.
+
+This change reliably fixed the problem on a system with multiple devices
+on a single bus. Example log where the device on address 0x18 (ADM1021)
+and on address 0x4c (ADT7461A) both had the alert line asserted:
+
+smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0
+smbus_alert 3-000c: no driver alert()!
+smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0

+Subject: spi: spi-fsl-lpspi: Fix scldiv calculation
+
+From: Stefan Wahren <wahrenst@gmx.net>
+
+[ Upstream commit 730bbfaf7d4890bd99e637db7767dc68cfeb24e7 ]
+
+The effective SPI clock frequency should never exceed speed_hz
+otherwise this might result in undefined behavior of the SPI device.
+
+Currently the scldiv calculation could violate this constraint.
+For the example parameters perclk_rate = 24 MHz and speed_hz = 7 MHz,
+the function fsl_lpspi_set_bitrate will determine perscale = 0 and
+scldiv = 1, which is a effective SPI clock of 8 MHz.
+
+So fix this by rounding up the quotient of perclk_rate and speed_hz.
+While this never change within the loop, we can pull this out.

+Subject: spi: spidev: Add missing spi_device_id for bh2228fv
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit e4c4638b6a10427d30e29d22351c375886025f47 ]
+
+When the of_device_id entry for "rohm,bh2228fv" was added, the
+corresponding spi_device_id was forgotten, causing a warning message
+during boot-up:
+
+ SPI driver spidev has no spi_device_id for rohm,bh2228fv
+
+Fix module autoloading and shut up the warning by adding the missing
+entry.
