2024-05-06wifi: iwlwifi: mvm: trigger link selection upon TTLM start/endMiri Korenblit
When non default TTLM is applied, mac80211 may force us to use a specific link (For example, if the only active link becomes a dormant link, mac80211 will pick the first usable link and set it as active). When default TTLM is applied, we have new usable links that we might want to select. Therefore, trigger MLO scan and link selection upon change in TTLM.

2024-05-06wifi: iwlwifi: mvm: don't always unblock EMLSRMiri Korenblit
When an event occurs to unblock EMLSR, the code attempts to re-enable EMLSR. However, the current implementation always tries to activate EMLSR, regardless of whether the blocker was set before the unblocking event or not. If EMLSR was already unblocked, there is no need to re-activate it.

2024-05-06wifi: iwlwifi: cleanup EMLSR when BT is active handlingMiri Korenblit
BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the vif from using EMLSR with a different link pair. In addition, storing it in mvmvif:disable_esr_reason requires extracting the BT Coex bit before checking if EMLSR is blocked or not for a specific vif. Therefore, change the BT Coex bit to be an exit reason and not a blocker. On link selection, EMLSR mode will be re-calculated for the 2.4 GHz link instead of checking that bit.

2024-05-06EDAC/synopsys: Fix ECC status and IRQ control race conditionSerge Semin
The race condition around the ECCCLR register access happens in the IRQ disable method called in the device remove() procedure and in the ECC IRQ handler: 1. Enable IRQ: a. ECCCLR = EN_CE | EN_UE 2. Disable IRQ: a. ECCCLR = 0 3. IRQ handler: a. ECCCLR = CLR_CE | CLR_CE_CNT | CLR_CE | CLR_CE_CNT b. ECCCLR = 0 c. ECCCLR = EN_CE | EN_UE So if the IRQ disabling procedure is called concurrently with the IRQ handler method the IRQ might be actually left enabled due to the statement 3c. The root cause of the problem is that ECCCLR register (which since v3.10a has been called as ECCCTL) has intermixed ECC status data clear flags and the IRQ enable/disable flags. Thus the IRQ disabling (clear EN flags) and handling (write 1 to clear ECC status data) procedures must be serialised around the ECCCTL register modification to prevent the race. So fix the problem described above by adding the spin-lock around the ECCCLR modifications and preventing the IRQ-handler from modifying the IRQs enable flags (there is no point in disabling the IRQ and then re-enabling it again within a single IRQ handler call, see the statements 3a/3b and 3c above).

2024-05-06net: microchip: lan743x: Reduce PTP timeout on HW failureRengarajan S
The PTP_CMD_CTL is a self clearing register which controls the PTP clock values. In the current implementation driver waits for a duration of 20 sec in case of HW failure to clear the PTP_CMD_CTL register bit. This timeout of 20 sec is very long to recognize a HW failure, as it is typically cleared in one clock(<16ns). Hence reducing the timeout to 1 sec would be sufficient to conclude if there is any HW failure observed. The usleep_range will sleep somewhere between 1 msec to 20 msec for each iteration. By setting the PTP_CMD_CTL_TIMEOUT_CNT to 50 the max timeout is extended to 1 sec.

In the former commits, the spurious interrupt events are suppressed as possible, by unset bus-reset event from the set of handled irq. The change was written with the less-intrusive style, thus it firstly works at the second time to handle the event. But it is slightly inconvenient. This commit adds the event for the initial set of irq to handle. As a result, the event can be handled even if it is the first time. The change has a benefit that the OHCI_PARAM_DEBUG_BUSRESETS bit in debug module parameter is always effective.

2024-05-06firewire: core/cdev: add tracepoints events for asynchronous phy packetTakashi Sakamoto
In IEEE 1394 bus, the type of asynchronous packet without any offset to node address space is called as phy packet. The destination of packet is IEEE 1394 phy itself. This type of packet is used for several purposes, mainly for selfID at the state of bus reset, to force selection of root node, and to adjust gap count. This commit adds tracepoints events for the type of asynchronous outbound packet. Like asynchronous outbound transaction packets, a pair of events are added to trace initiation and completion of transmission. In the case that the phy packet is sent by kernel API, the match between the initiation and completion is not so easy, since the data of 'struct fw_packet' is allocated statically. In the case that it is sent by userspace applications via cdev, the match is easy, since the data is allocated per each. This example is for Remote Access Packet by lsfirewirephy command in linux-firewire-utils: async_phy_outbound_initiate: \ packet=0xffff89fb34e42e78 generation=1 first_quadlet=0x00148200 \ second_quadlet=0xffeb7dff async_phy_outbound_complete: \ packet=0xffff89fb34e42e78 generation=1 status=1 timestamp=0x0619 Link: https://lore.kernel.org/r/20240430001404.734657-2-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>

2024-05-06firewire: core: option to log bus reset initiationAdam Goldman
Add a debug parameter to firewire-core, analogous to the one in firewire-ohci. When this is set to 1, log when we schedule, delay, or initiate a bus reset. Since FireWire bus resets can originate from any node on the bus, specific logging of the resets we initiate provides additional insight.

2024-05-06spi: pxa2xx: Drop linux/spi/pxa2xx_spi.hMark Brown
Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>: As Arnd suggested we may drop linux/spi/pxa2xx_spi.h as most of its content is being used solely internally to SPI subsystem (PXA2xx drivers). Hence this refactoring series with the additional win of getting rid of legacy documentation. Note, that we have the only user of a single plain integer field in the entire kernel for that. Switching to software nodes does not diminish any of type checking as we only pass an integer.
2024-05-06spi: dw: Auto-detect number of native CSMark Brown
Merge series from Serge Semin <fancer.lancer@gmail.com>: The main goal of the short series is to provide a procedure implementing the auto-detection of the number of native Chip-Select signals supported by the controller. The suggested algorithm is straightforward. It relies on the fact that the SER register writable flags reflects the actual number of available native chip-select signals. So the DW APB/AHB SSI driver now tests the SER register for having the writable bits, calculates the number of CS signals based on the number of set flags and then initializes the num_cs private data field based on that, which then will be passed to the SPI-core subsystem indicating the number of supported hardware chip-selects. The implemented procedure will be useful for the DW SSI device nodes not having the explicitly set "num-cs" property. In case if the property is specified it will be utilized instead of the auto-detection procedure. Besides of that a small cleanup patch is introduced in the head of the series. It converts the driver to using the BITS_TO_BYTES() macro instead of the hard-coded DIV_ROUND_UP()-based calculation of the number of bytes-per-transfer-word.
2024-05-06regulator: new API for voltage reference suppliesMark Brown
Merge series from David Lechner <dlechner@baylibre.com>: In the IIO subsystem, we noticed a pattern in many drivers where we need to get, enable and get the voltage of a supply that provides a reference voltage. In these cases, we only need the voltage and not a handle to the regulator. Another common pattern is for chips to have an internal reference voltage that is used when an external reference is not available. There are also a few drivers outside of IIO that do the same. So we would like to propose a new regulator consumer API to handle these specific cases to avoid repeating the same boilerplate code in multiple drivers. As an example of how these functions are used, I have included a few patches to consumer drivers. But to avoid a giant patch bomb, I have omitted the iio/adc and iio/dac patches I have prepared from this series. I will send those separately but these will add 36 more users of devm_regulator_get_enable_read_voltage() in addition to the 6 here. In total, this will eliminate nearly 1000 lines of similar code and will simplify writing and reviewing new drivers in the future.
