2025-06-23spi: cadence-qspi: remove system-wide suspend helper calls from runtime PM hookstoradex_ti-linux-6.1.yThéo Lebrun
The ->runtime_suspend() and ->runtime_resume() callbacks are not expected to call spi_controller_suspend() and spi_controller_resume(). Remove calls to those in the cadence-qspi driver. Those helpers have two roles currently: - They stop/start the queue, including dealing with the kworker. - They toggle the SPI controller SPI_CONTROLLER_SUSPENDED flag. It requires acquiring ctlr->bus_lock_mutex. Step one is irrelevant because cadence-qspi is not queued. Step two however has two implications: - A deadlock occurs, because ->runtime_resume() is called in a context where the lock is already taken (in the ->exec_op() callback, where the usage count is incremented). - It would disallow all operations once the device is auto-suspended. Here is a brief call tree highlighting the mutex deadlock: spi_mem_exec_op() ... spi_mem_access_start() mutex_lock(&ctlr->bus_lock_mutex) cqspi_exec_mem_op() pm_runtime_resume_and_get() cqspi_resume() spi_controller_resume() mutex_lock(&ctlr->bus_lock_mutex) ... spi_mem_access_end() mutex_unlock(&ctlr->bus_lock_mutex) ...

[ Upstream commit fb98bd0a13de2c9d96cb5c00c81b5ca118ac9d71 ] The SPI interface is activated before the CPOL setting is applied. In that moment, the clock idles high and CS goes low. After a short delay, CPOL and other settings are applied, which may cause the clock to change state and idle low. This transition is not part of a clock cycle, and it can confuse the receiving device. To prevent this unexpected transition, activate the interface while CPOL and the other settings are being applied.

2025-06-04octeontx2-pf: Fix page pool cache index corruption.Ratheesh Kannoth
commit 88e69af061f2e061a68751ef9cad47a674527a1b upstream. The access to page pool `cache' array and the `count' variable is not locked. Page pool cache access is fine as long as there is only one consumer per pool. octeontx2 driver fills in rx buffers from page pool in NAPI context. If system is stressed and could not allocate buffers, refiiling work will be delegated to a delayed workqueue. This means that there are two cosumers to the page pool cache. Either workqueue or IRQ/NAPI can be run on other CPU. This will lead to lock less access, hence corruption of cache pool indexes. To fix this issue, NAPI is rescheduled from workqueue context to refill rx buffers.

commit 49fa4b0d06705a24a81bb8be6eb175059b77f0a7 upstream. octeontx2 driver calls page_pool_create() during driver probe() and fails if queue size > 32k. Page pool infra uses these buffers as shock absorbers for burst traffic. These pages are pinned down over time as working sets varies, due to the recycling nature of page pool, given page pool (currently) don't have a shrinker mechanism, the pages remain pinned down in ptr_ring. Instead of clamping page_pool size to 32k at most, limit it even more to 2k to avoid wasting memory. This have been tested on octeontx2 CN10KA hardware.

commit 81100b9a7b0515132996d62a7a676a77676cb6e3 upstream. On (H)SCIF with a Baud Rate Generator for External Clock (BRG), there are multiple ways to configure the requested serial speed. If firmware uses a different method than Linux, and if any debug info is printed after the Bit Rate Register (SCBRR) is restored, but before termios is reconfigured (which configures the alternative method), the system may lock-up during resume. Fix this by saving and restoring the contents of the BRG Frequency Division (SCDL) and Clock Select (SCCKS) registers as well. Also save and restore the HSCIF's Sampling Rate Register (HSSRR), which configures the sampling point, and the SCIFA/SCIFB's Serial Port Control and Data Registers (SCPCR/SCPDR), which configure the optional control flow signals. After this, all registers that are not saved/restored are either: - read-only, - write-only, - status registers containing flags with clear-after-set semantics, - FIFO Data Count Trigger registers, which do not matter much for the serial console.

[ Upstream commit 8a30a6d35a11ff5ccdede7d6740765685385a917 ] The XSPI mode implementation in this driver still uses the EOQ flag to signal the last word in a transmission and deassert the PCS signal. However, at speeds lower than ~200kHZ, the PCS signal seems to remain asserted even when SR[EOQF] = 1 indicates the end of a transmission. This is a problem for target devices which require the deassertation of the PCS signal between transfers. Hence, this commit 'forces' the deassertation of the PCS by stopping the module through MCR[HALT] after completing a new transfer. According to the reference manual, the module stops or transitions from the Running state to the Stopped state after the current frame, when any one of the following conditions exist: - The value of SR[EOQF] = 1. - The chip is in Debug mode and the value of MCR[FRZ] = 1. - The value of MCR[HALT] = 1. This shouldn't be done if the last transfer in the message has cs_change set.

[ Upstream commit bbd95160a03dbfcd01a541f25c27ddb730dfbbd5 ] The ice_vc_repr_add_mac() function indicates that it does not store the MAC address filters in the firmware. However, it still increments vf->num_mac. This is incorrect, as vf->num_mac should represent the number of MAC filters currently programmed to firmware. Indeed, we only perform this increment if the requested filter is a unicast address that doesn't match the existing vf->hw_lan_addr. In addition, ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This results in the counter becoming out of sync with the actual count. As it turns out, vf->num_mac is currently only used in legacy made without port representors. The single place where the value is checked is for enforcing a filter limit on untrusted VFs. Upcoming patches to support VF Live Migration will use this value when determining the size of the TLV for MAC address filters.

Retain the xen_initial_domain() check, and use that for an additional check when the event channel is 0.

2025-06-04pinctrl: meson: define the pull up/down resistor value as 60 kOhmMartin Blumenstingl
[ Upstream commit e56088a13708757da68ad035269d69b93ac8c389 ] The public datasheets of the following Amlogic SoCs describe a typical resistor value for the built-in pull up/down resistor: - Meson8/8b/8m2: not documented - GXBB (S905): 60 kOhm - GXL (S905X): 60 kOhm - GXM (S912): 60 kOhm - G12B (S922X): 60 kOhm - SM1 (S905D3): 60 kOhm The public G12B and SM1 datasheets additionally state min and max values: - min value: 50 kOhm for both, pull-up and pull-down - max value for the pull-up: 70 kOhm - max value for the pull-down: 130 kOhm Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality 60 kOhm is closer to the actual value than 1 Ohm.

[ Upstream commit 749b5b279e5636cdcef51e15d67b77162cca6caa ] We have a few reports of sc7180-trogdor-pompom devices that have a panel in them that IDs as STA 0x0004 and has the following raw EDID: 00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00 10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28 1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20 55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe 00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6 We've been unable to locate a datasheet for this panel and our partner has not been responsive, but all Starry eDP datasheets that we can find agree on the same timing (delay_100_500_e200) so it should be safe to use that here instead of the super conservative timings. We'll still go a little extra conservative and allow `hpd_absent` of 200 instead of 100 because that won't add any real-world delay in most cases. We'll associate the string from the EDID ("116KHD024006") with this panel. Given that the ID is the suspicious value of 0x0004 it seems likely that Starry doesn't always update their IDs but the string will still work to differentiate if we ever need to in the future.

2025-06-04wifi: ath9k: return by of_get_mac_addressRosen Penev
[ Upstream commit dfffb317519f88534bb82797f055f0a2fd867e7b ] When using nvmem, ath9k could potentially be loaded before nvmem, which loads after mtd. This is an issue if DT contains an nvmem mac address. If nvmem is not ready in time for ath9k, -EPROBE_DEFER is returned. Pass it to _probe so that ath9k can properly grab a potentially present MAC address.

2025-06-04regulator: ad5398: Add device tree supportIsaac Scott
[ Upstream commit 5a6a461079decea452fdcae955bccecf92e07e97 ] Previously, the ad5398 driver used only platform_data, which is deprecated in favour of device tree. This caused the AD5398 to fail to probe as it could not load its init_data. If the AD5398 has a device tree node, pull the init_data from there using of_get_regulator_init_data.

rtw8822b_set_tx_power_index_by_rate [ Upstream commit 00451eb3bec763f708e7e58326468c1e575e5a66 ] Some users want to plug two identical USB devices at the same time. This static variable could theoretically cause them to use incorrect TX power values. Move the variable to the caller and pass a pointer to it to rtw8822b_set_tx_power_index_by_rate().

[ Upstream commit 3d3e28feca7ac8c6cf2a390dbbe1f97e3feb7f36 ] Occasionally there is an EPROTO error during firmware download. This error is converted to EAGAIN in the download function. But nobody tries again and so device probe fails. Implement download retry to fix this. This error was observed (and fix tested) on a tbs2910 board [1] with an embedded RTL8188EU (0bda:8179) device behind a USB hub.
