2023-10-27firmware_loader: Abort all upcoming firmware load request once reboot triggeredMukesh Ojha
There could be following scenario where there is a ongoing reboot is going from processA which tries to call all the reboot notifier callback and one of them is firmware reboot call which tries to abort all the ongoing firmware userspace request under fw_lock but there could be another processB which tries to do request firmware, which came just after abort done from ProcessA and ask for userspace to load the firmware and this can stop the ongoing reboot ProcessA to stall for next 60s(default timeout) which may not be expected behaviour everyone like to see, instead we should abort any firmware load request which came once firmware knows about the reboot through notification.

2023-10-27greybus: Add BeaglePlay Linux DriverAyush Singh
Add the Greybus host driver for BeaglePlay board by BeagleBoard.org. The current greybus setup involves running SVC in a user-space application (GBridge) and using netlink to communicate with kernel space. GBridge itself uses wpanusb kernel driver, so the greybus messages travel from kernel space (gb_netlink) to user-space (GBridge) and then back to kernel space (wpanusb) before reaching CC1352. This driver directly communicates with CC1352 (running SVC Zephyr application). Thus, it simplifies the complete greybus setup eliminating user-space GBridge. This driver is responsible for the following: - Start SVC (CC1352) on driver load. - Send/Receive Greybus messages to/from CC1352 using HDLC over UART. - Print Logs from CC1352. - Stop SVC (CC1352) on driver load.

2023-10-27Revert "nvmem: add new config option"Rafał Miłecki
This reverts commit 517f14d9cf3533d5ab4fded195ab6f80a92e378f. Config option "no_of_node" is no longer needed since adding a more explicit and targeted option "add_legacy_fixed_of_cells". That "no_of_node" config option was needed *earlier* to help mtd's case. DT nodes of MTD partitions (that are also NVMEM devices) may contain subnodes. Those SHOULD NOT be treated as NVMEM fixed cells. To prevent NVMEM core code from parsing subnodes a "no_of_node" option was added (and set to true in mtd) to make for_each_child_of_node() in NVMEM a no-op. That was a bit hacky because it was messing with "of_node" pointer to achieve some side-effect. With the introduction of "add_legacy_fixed_of_cells" config option things got more explicit. MTD subsystem simply tells NVMEM when to look for fixed cells and there is no need to hack "of_node" pointer anymore.

2023-10-27PCI: qcom-ep: Add dedicated callback for writing to DBI2 registersManivannan Sadhasivam
The DWC core driver exposes the write_dbi2() callback for writing to the DBI2 registers in a vendor-specific way. On the Qcom EP platforms, the DBI_CS2 bit in the ELBI region needs to be asserted before writing to any DBI2 registers and deasserted once done. So, let's implement the callback for the Qcom PCIe EP driver so that the DBI2 writes are correctly handled in the hardware. Without this callback, the DBI2 register writes like BAR size won't go through and as a result, the default BAR size is set for all BARs.

2023-10-27staging: fbtft: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. The function fbtft_driver_remove_pdev() (that exists several times as it's part of a macro expansion) returns zero unconditionally, so it can be trivially converted to return void without semantic changes.

2023-10-27staging: olpc_dcon: Remove I2C_CLASS_DDC supportHeiner Kallweit
olpc_dcon is the only remaining i2c client device driver declaring I2C_CLASS_DDC support after the legacy eeprom driver has been removed. olpc_dcon is only used on olpc devices, connected to an i2c adapter driven by scx200_acb. This adapter driver declares support for I2C_CLASS_HWMON and I2C_CLASS_SPD. Therefore we can safely drop I2C_CLASS_DDC support in olpc_dcon. That's the last step before I2C_CLASS_DDC can be removed in general. This patch is solely based on documentation, and I don't have an olpc device for testing. Therefore some testing would be appreciated before patch is applied.

2023-10-27usb: raw-gadget: report suspend, resume, reset, and disconnect eventsAndrey Konovalov
Update USB_RAW_IOCTL_EVENT_FETCH to also report suspend, resume, reset, and disconnect events. This allows the code that emulates a USB device via Raw Gadget to handle these events. For example, the device can restart enumeration when it gets reset. Also do not print a WARNING when the event queue overflows. With these new events being queued, the queue might overflow if the device emulation code stops fetching events. Also print debug messages when a non-control event is received.

2023-10-27usb: raw-gadget: don't disable device if usb_ep_queue failsAndrey Konovalov
During device operation, the host might decide to reset a device emulated via Raw Gadget. In this case, if the device emulation code has endpoint requests queued, usb_ep_queue will fail with -ESHUTDOWN. Currently, this disables the Raw Gadget device and makes the emulation code unable to proceed. Do not disable the Raw Gadget device if usb_ep_queue fails.

2023-10-27usb: raw-gadget: properly handle interrupted requestsAndrey Konovalov
Currently, if a USB request that was queued by Raw Gadget is interrupted (via a signal), wait_for_completion_interruptible returns -ERESTARTSYS. Raw Gadget then attempts to propagate this value to userspace as a return value from its ioctls. However, when -ERESTARTSYS is returned by a syscall handler, the kernel internally restarts the syscall. This doesn't allow userspace applications to interrupt requests queued by Raw Gadget (which is required when the emulated device is asked to switch altsettings). It also violates the implied interface of Raw Gadget that a single ioctl must only queue a single USB request. Instead, make Raw Gadget do what GadgetFS does: check whether the request was interrupted (dequeued with status == -ECONNRESET) and report -EINTR to userspace.
