2023-10-28hwmon: (pmbus/max31785) Add delay between bus accessesLakshmi Yadlapati
The MAX31785 has shown erratic behaviour across multiple system designs, unexpectedly clock stretching and NAKing transactions. Experimentation shows that this seems to be triggered by a register access directly back to back with a previous register write. Experimentation also shows that inserting a small delay after register writes makes the issue go away. Use a similar solution to what the max15301 driver does to solve the same problem. Create a custom set of bus read and write functions that make sure that the delay is added.

2023-10-28hwmon: (ina3221) Add support for channel summation disableNinad Malwade
The INA3221 allows the Critical alert pin to be controlled by the summation control function. This function adds the single shunt-voltage conversions for the desired channels in order to compare the combined sum to the programmed limit. The Shunt-Voltage Sum Limit register contains the programmed value that is compared to the value in the Shunt-Voltage Sum register in order to determine if the total summed limit is exceeded. If the shunt-voltage sum limit value is exceeded, the Critical alert pin pulls low. For the summation limit to have a meaningful value, we have to use the same shunt-resistor value on all included channels. Unless equal shunt-resistor values are used for each channel, the summation control function cannot be used and it is not enabled by the driver. To address this, add support to disable the summation of specific channels via device tree property "ti,summation-disable". The channel which has this property would be excluded from the calculation of summation control function. For example, summation control function calculates Shunt-Voltage Sum as: - input_shunt_voltage_summation = input_shunt_voltage_channel1 + input_shunt_voltage_channel2 + input_shunt_voltage_channel3 If we want the summation to only use channel1 and channel3, we can add 'ti,summation-disable' property in device tree node for channel2. Then the calculation will skip channel2. - input_shunt_voltage_summation = input_shunt_voltage_channel1 + input_shunt_voltage_channel3 Note that we only want the channel to be skipped for summation control function rather than completely disabled. Therefore, even if we add the property 'ti,summation-disable', the channel is still enabled and functional. Finally, create debugfs entries that display if summation is disabled for each of the channels.

2023-10-28block: move bdev_mark_dead out of disk_check_media_changeChristoph Hellwig
disk_check_media_change is mostly called from ->open where it makes little sense to mark the file system on the device as dead, as we are just opening it. So instead of calling bdev_mark_dead from disk_check_media_change move it into the few callers that are not in an open instance. This avoid calling into bdev_mark_dead and thus taking s_umount with open_mutex held.

2023-10-28bcache: Fixup error handling in register_cache()Jan Kara
Coverity has noticed that the printing of error message in register_cache() uses already freed bdev_handle to get to bdev. In fact the problem has been there even before commit "bcache: Convert to bdev_open_by_path()" just a bit more subtle one - cache object itself could have been freed by the time we looked at ca->bdev and we don't hold any reference to bdev either so even that could in principle go away (due to device unplug or similar).

2023-10-28usb: gadget: uvc: Add missing initialization of ssp config descriptorShuzhen Wang
In case the uvc gadget is super speed plus, the corresponding config descriptor wasn't initialized. As a result, the host will not recognize the devices when using super speed plus connection. This patch initializes them to super speed descriptors.

2023-10-27acpi: Move common tables helper functions to common libDave Jiang
Some of the routines in ACPI driver/acpi/tables.c can be shared with parsing CDAT. CDAT is a device-provided data structure that is formatted similar to a platform provided ACPI table. CDAT is used by CXL and can exist on platforms that do not use ACPI. Split out the common routine from ACPI to accommodate platforms that do not support ACPI and move that to /lib. The common routines can be built outside of ACPI if FIRMWARE_TABLES is selected.

Add read_cdat_data() call in cxl_switch_port_probe() to allow reading of CDAT data for CXL switches. read_cdat_data() needs to be adjusted for the retrieving of the PCIe device depending on if the passed in port is endpoint or switch.

A CDAT table is available from a CXL device. The table is read by the driver and cached in software. With the CXL subsystem needing to parse the CDAT table, the checksum should be verified. Add checksum verification after the CDAT table is read from device.
