2022-11-29mmc: sdhci: Fix voltage switch delayAdrian Hunter
Commit 20b92a30b561 ("mmc: sdhci: update signal voltage switch code") removed voltage switch delays from sdhci because mmc core had been enhanced to support them. However that assumed that sdhci_set_ios() did a single clock change, which it did not, and so the delays in mmc core, which should have come after the first clock change, were not effective. Fix by avoiding re-configuring UHS and preset settings when the clock is turning on and the settings have not changed. That then also avoids the associated clock changes, so that then sdhci_set_ios() does a single clock change when voltage switching, and the mmc core delays become effective. To do that has meant keeping track of driver strength (host->drv_type), and cases of reinitialization (host->reinit_uhs). Note also, the 'turning_on_clk' restriction should not be necessary but is done to minimize the impact of the change on stable kernels.

2022-11-29usb: dwc3: Fix race between dwc3_set_mode and __dwc3_set_modeSven Peter
dwc->desired_dr_role is changed by dwc3_set_mode inside a spinlock but then read by __dwc3_set_mode outside of that lock. This can lead to a race condition when very quick successive role switch events happen: CPU A dwc3_set_mode(DWC3_GCTL_PRTCAP_HOST) // first role switch event spin_lock_irqsave(&dwc->lock, flags); dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_HOST spin_unlock_irqrestore(&dwc->lock, flags); queue_work(system_freezable_wq, &dwc->drd_work); CPU B __dwc3_set_mode // .... spin_lock_irqsave(&dwc->lock, flags); // desired_dr_role is DWC3_GCTL_PRTCAP_HOST dwc3_set_prtcap(dwc, dwc->desired_dr_role); spin_unlock_irqrestore(&dwc->lock, flags); CPU A dwc3_set_mode(DWC3_GCTL_PRTCAP_DEVICE) // second event spin_lock_irqsave(&dwc->lock, flags); dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_DEVICE spin_unlock_irqrestore(&dwc->lock, flags); CPU B (continues running __dwc3_set_mode) switch (dwc->desired_dr_role) { // DWC3_GCTL_PRTCAP_DEVICE // .... case DWC3_GCTL_PRTCAP_DEVICE: // .... ret = dwc3_gadget_init(dwc); We then have DWC3_GCTL.DWC3_GCTL_PRTCAPDIR = DWC3_GCTL_PRTCAP_HOST and dwc->current_dr_role = DWC3_GCTL_PRTCAP_HOST but initialized the controller in device mode. It's also possible to get into a state where both host and device are intialized at the same time. Fix this race by creating a local copy of desired_dr_role inside __dwc3_set_mode while holding dwc->lock.

Instead of immediately killing the user-process when a command submission times out, we wait a bit and give the user-process notification and let it try to close things gracefully, with the ability to retrieve debug information. - Enhance the EventFD mechanism. Add new events such as access to illegal address (RAZWI), page fault, device unavailable. In addition, change the event workqueue to be handled in a single-threaded workqueue. - Allow the control device to work during reset of the ASIC, to enable monitoring applications to continue getting the data. - Add handling for Gaudi2 with PCI revision 2. - Reduce severity of prints due to power/thermal events. - Change how we use the h/w to perform memory scrubbing in Gaudi2. - Multiple bug fixes, refactors and renames. * tag 'misc-habanalabs-next-2022-11-23' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (63 commits) habanalabs: fix VA range calculation habanalabs: fail driver load if EEPROM errors detected habanalabs: make print of engines idle mask more readable habanalabs: clear non-released encapsulated signals habanalabs: don't put context in hl_encaps_handle_do_release_sob() habanalabs: print context refcount value if hard reset fails habanalabs: add RMWREG32_SHIFTED to set a val within a mask habanalabs: fix rc when new CPUCP opcodes are not supported habanalabs/gaudi2: added memset for the cq_size register habanalabs: added return value check for hl_fw_dynamic_send_clear_cmd() habanalabs: increase the size of busy engines mask habanalabs/gaudi2: change memory scrub mechanism habanalabs: extend process wait timeout in device fine habanalabs: check schedule_hard_reset correctly habanalabs: reset device if still in use when released habanalabs/gaudi2: return to reset upon SM SEI BRESP error habanalabs/gaudi2: don't enable entries in the MSIX_GW table habanalabs/gaudi2: remove redundant firmware version check habanalabs/gaudi: fix print for firmware-alive event habanalabs: fix print for out-of-sync and pkt-failure events ...

2022-11-29net: microchip: vcap: Merge the vcap_ag_api_kunit.h into vcap_ag_api.hHoratiu Vultur
Currently there are 2 files that contain the keyfields, keys, actionfields and actions. First file is used by the kunit while the second one is used by VCAP api. The header file that is used by kunit is just a super set of the of the header file used by VCAP api. Therefore not to have duplicate information in different files which is also harder to maintain, create a single file that is used both by API and by kunit.

The MACH_INGENIC Kconfig option will be selected when building a kernel targeting Ingenic SoCs, but also when compiling a generic MIPS kernel that happens to support Ingenic SoCs. Therefore, if MACH_INGENIC is not set, we know that we're not even trying to build a generic kernel that supports these SoCs, and we can hide the options to compile the SoC-specific drivers.
